The primary symptom of laryngitis is a hoarse voice. Because laryngitis can have various causes, other signs and symptoms may vary. They can include

- Dry or sore throat

- Coughing (both a causal factor and a symptom of laryngitis)

- Frequent throat clearing

- Increased saliva production

- Dysphagia (difficulty swallowing)

- Sensation of swelling in the area of the larynx (discomfort in the front of the neck)

- Globus pharyngeus (feeling like there is a lump in the throat)

- Cold or flu-like symptoms (which, like a cough, may also be a causal factor for laryngitis)

- Swollen lymph nodes in the throat, chest, or face

- Fever

- General muscle pain (myalgia)

- Shortness of breath, predominantly in children

Aside from a hoarse-sounding voice, changes to pitch and volume may occur with laryngitis. Speakers may experience a lower or higher pitch than normal, depending on whether their vocal folds are swollen or stiff. They may also have breathier voices, as more air flows through the space between the vocal folds (the glottis), quieter volume and a reduced range.

Sialadenitis (sialoadenitis) is inflammation of a salivary gland. It may be subdivided temporally into acute, chronic and recurrent forms.

About 60 percent of initial attacks of dacryocystitis will recur. Individuals with a poorly functioning immune system (immunocompromised) may develop orbital cellulitis, which may lead to optic neuritis, proptosis, motility abnormalities, or blindness.

Neoplasm should be considered in any patient presenting with NLD obstruction.In patients with an atypical presentation, including younger age and male gender, further workup is appropriate. Bloody punctal discharge or lacrimal sac distension above the medial canthal tendon is also highly suggestive of neoplasm.

In chronic recurrent sialadenitis or chronic sclerosing sialadenitis, acute attacks are managed with conservative therapies such as hydration, analgesics (mainly NSAIDs), sialogogues to stimulate salivary secretion, and regular, gentle gland massage. If infection is present, appropriate cultures should be obtained, followed by empirical antibiotic therapy initially, for example amoxicillin/clavulanate or clindamycin which cover oral flora.

If there are attacks more than approximately 3 times per year or severe attacks, surgical excision of the affected gland should be considered.

As with similar cases of canalicular obstruction, dislodged punctal and canalicular plugs can migrate to and occlude the NLD.

Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of lacrimal sac. The term derives from the Greek "dákryon" (tear), "cysta" (sac), and "-itis" (inflammation). It causes pain, redness, and swelling over the inner aspect of the lower eyelid and epiphora. When nasolacrimal duct obstruction is secondary to a congenital barrier it is referred to as dacrocystocele. It is most commonly caused by "Staphylococcus aureus" and "Streptococcus pneumoniae". The most common complication is corneal ulceration, frequently in association with "S. pneumoniae". The mainstays of treatment are oral antibiotics, warm compresses, and relief of nasolacrimal duct obstruction by dacryocystorhinostomy.

Sinusitis (or rhinosinusitis) is defined as an inflammation of the mucous membrane that lines the paranasal sinuses and is classified chronologically into several categories:

- Acute rhinosinusitis – A new infection that may last up to four weeks and can be subdivided symptomatically into severe and non-severe. Some use definitions up to 12 weeks.

- Recurrent acute rhinosinusitis – Four or more full episodes of acute sinusitis that occur within one year

- Subacute rhinosinusitis – An infection that lasts between four and 12 weeks, and represents a transition between acute and chronic infection

- Chronic rhinosinusitis – When the signs and symptoms last for more than 12 weeks.

- Acute exacerbation of chronic rhinosinusitis – When the signs and symptoms of chronic rhinosinusitis exacerbate, but return to baseline after treatment

All these types of sinusitis have similar symptoms, and are thus often difficult to distinguish. Acute sinusitis is very common. Roughly ninety percent of adults have had sinusitis at some point in their life.

Headache/facial pain or pressure of a dull, constant, or aching sort over the affected sinuses is common with both acute and chronic stages of sinusitis. This pain is typically localized to the involved sinus and may worsen when the affected person bends over or when lying down. Pain often starts on one side of the head and progresses to both sides.

Acute sinusitis may be accompanied by thick nasal discharge that is usually green in color and may contain pus (purulent) and/or blood. Often a localized headache or toothache is present, and it is these symptoms that distinguish a sinus-related headache from other types of headaches, such as tension and migraine headaches. Another way to distinguish between toothache and sinusitis is that the pain in sinusitis is usually worsened by tilting the head forwards and with valsalva maneuvers.

Infection of the eye socket is possible, which may result in the loss of sight and is accompanied by fever and severe illness. Another possible complication is the infection of the bones (osteomyelitis) of the forehead and other facial bones – Pott's puffy tumor.

Sinus infections can also cause middle ear problems due to the congestion of the nasal passages. This can be demonstrated by dizziness, "a pressurized or heavy head", or vibrating sensations in the head. Post-nasal drip is also a symptom of chronic rhinosinusitis.

Halitosis (bad breath) is often stated to be a symptom of chronic rhinosinusitis; however, gold standard breath analysis techniques have not been applied. Theoretically, there are several possible mechanisms of both objective and subjective halitosis that may be involved.

A 2004 study suggested that up to 90% of "sinus headaches" are actually migraines. The confusion occurs in part because migraine involves activation of the trigeminal nerves, which innervate both the sinus region and the meninges surrounding the brain. As a result, it is difficult to accurately determine the site from which the pain originates. People with migraines do not typically have the thick nasal discharge that is a common symptom of a sinus infection.

Not all acute diseases or injuries are severe, and vice versa. For example, a mild stubbed toe is an acute injury. Similarly, many acute upper respiratory infections and acute gastroenteritis cases in adults are mild and usually resolve within a few days or weeks.

The term "acute" is also included in the definition of several diseases, such as severe acute respiratory syndrome, acute leukemia, acute myocardial infarction, and acute hepatitis. This is often to distinguish diseases from their chronic forms, such as chronic leukemia, or to highlight the sudden onset of the disease, such as acute myocardial infarct.

Many people who have chronic gastritis do not experience any noticeable symptoms. Those who do, claim to experience one or several of the following: upper abdominal pain, indigestion, bloating, nausea, vomiting, belching, loss of appetite, and weight loss. Stomach bleeding or black stool has been reported in extreme cases.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is characterized by pelvic or perineal pain without evidence of urinary tract infection, lasting longer than 3 months, as the key symptom. Symptoms may wax and wane. Pain can range from mild to debilitating. Pain may radiate to the back and rectum, making sitting uncomfortable. Pain can be present in the perineum, testicles, tip of penis, pubic or bladder area. Dysuria, arthralgia, myalgia, unexplained fatigue, abdominal pain, constant burning pain in the penis, and frequency may all be present. Frequent urination and increased urgency may suggest interstitial cystitis (inflammation centred in bladder rather than prostate). Post-ejaculatory pain, mediated by nerves and muscles, is a hallmark of the condition, and serves to distinguish CP/CPPS patients from men with BPH or normal men. Some patients report low libido, sexual dysfunction and erectile difficulties.

Since 1992, chronic gastritis lesions are classified according to the Sydney system.

Chronic idiopathic constipation is similar to constipation-predominant irritable bowel syndrome (IBS-C); however, people with CIC do not have other symptoms of IBS, such as abdominal pain. Diagnosing CIC can be difficult as other syndromes must be ruled out as there is no physiological cause for CIC. Doctors will typically look for other symptoms, such as blood in stool, weight loss, low blood count, or other symptoms.

To be considered functional constipation, symptoms must be present at least a fourth of the time.

Possible causes are:

- Anismus

- Descending perineum syndrome

- Other inability or unwillingness to control the external anal sphincter, which normally is under voluntary control

- A poor diet

- An unwillingness to defecate

- Nervous reactions, including prolonged and/or chronic stress and anxiety, that close the internal anal sphincter, a muscle that is not under voluntary control

- Deeper psychosomatic disorders which sometimes affect digestion and the absorption of water in the colon

There is also possibility of presentation with other comorbid symptoms such as headache, especially in children.

In medicine, describing a disease as acute denotes that it is of short and, as a corollary of that, of recent . The quantitation of how much time constitutes "short" and "recent" varies by disease and by context, but the core denotation of "acute" is always qualitatively in contrast with "chronic", which denotes long-lasting disease (for example, in acute leukemia and chronic leukemia). In addition, "acute" also often connotes two other meanings: onset and , such as in acute myocardial infarction (EMI), where suddenness and severity are both established aspects of the meaning. It thus often connotes that the condition is fulminant (as in the EMI example), but not always (as in acute rhinitis, which is usually synonymous with the common cold). The one thing that acute MI and acute rhinitis have in common is that they are not chronic. They can happen again (as in recurrent pneumonia, that is, multiple acute pneumonia episodes), but they are not the same ongoing for months or years (unlike chronic obstructive pulmonary disease, which is).

A noncount sense of "acute disease" refers to the acute phase, that is, a short course, of any disease entity. For example, in an article on ulcerative enteritis in poultry, the author says, "in acute disease there may be increased mortality without any obvious signs", referring to the acute form or phase of ulcerative enteritis.

Nasal vestibulitis is the diffuse dermatitis of nasal vestibule. It is often caused by "Staphylococcus aureus." It may be secondary to chronic rhinorrhea, nose picking or viral infections. In acute vestibulitis, the skin is red, swollen and tender. In chronic vestibulitis, induration of vestibular skin and crusting is seen. It is treated by cleaning the nasal vestibule of all crusts with a cotton applicator soaked in hydrogen peroxide. Antibiotic steroid ointment is sometimes helpful. Chronic fissures are treated by cautery.

Diagnosis of epiphora is clinical by history presentation and observation of the lids. Fluorescein dye can be used to examine for punctal reflux by pressing on the canaliculi in which the clinician should note resistance of reflux as it irrigates through the punctum into the nose.

Functional constipation, known as chronic idiopathic constipation (CIC), is constipation that does not have a physical (anatomical) or physiological (hormonal or other body chemistry) cause. It may have a neurological, psychological or psychosomatic cause. A person with functional constipation may be healthy, yet has difficulty defecating.

Causes of epiphora are any that cause either overproduction of tears or decreased drainage of tears, resulting in tearing onto the cheek. This can be due to ocular irritation and inflammation (including trichiasis and entropion) or an obstructed tear outflow tract which is divided according to its anatomical location (i.e. ectropion, punctal, canalicular or nasolacrimal duct obstruction). The latter is often due to aging (a spontaneous process), conjunctivochalasis, infection (i.e. dacryocystitis), rhinitis, and in neonates or infants, failure of the nasolacrimal duct to open. Another cause could be poor reconstruction of the nasolacrimal duct system after trauma to the area. Cause of trauma could be facial fractures (including nasoethmoid fractures or maxillary Le Fort fractures), and soft tissue trauma involving the nose and/or the eyelid.

This condition is often frustrating or irritating. A systematic review studying the usage of punctal plugs for treatment of dry eye reported a few cases of epiphora among participants.

A 2016 review paper found that although the peripheral nervous system is responsible for starting the condition, the central nervous system (CNS) is responsible for continuing the pain even without continuing input from the peripheral nerves.

Tension-type headache pain is often described as a constant pressure, as if the head were being squeezed in a vise. The pain is frequently present on both sides of the head at the same time. Tension-type headache pain is typically mild to moderate, but may be severe.

According to the third edition of the International Classification of Headache Disorders, the attacks must meet the following criteria:

- A duration of between 30 minutes and 7 days.

- At least two of the following four characteristics:

- bilateral location

- pressing or tightening (non-pulsating) quality

- mild or moderate intensity

- not aggravated by routine physical activity such as walking or climbing stairs

- Both of the following:

- no nausea or vomiting

- no more than one of photophobia (sensitivity to bright light) or phonophobia (sensitivity to loud sounds)

Tension-type headaches may be accompanied by tenderness of the scalp on manual pressure during an attack.

Based on frequency, tension-type headaches can be sub-classified as

- Infrequent episodic: occurring less than once per month on average, or less than 12 episodes a year;

- Frequent episodic: occurring between 1-14 times per month on average for at least 3 months;

- Chronic: occurring 15 times a month for at least 3 months (CTTH - "chronic tension-type headache").

Viral conjunctivitis is often associated with an infection of the upper respiratory tract, a common cold, or a sore throat. Its symptoms include excessive watering and itching. The infection usually begins with one eye, but may spread easily to the other.

Viral conjunctivitis shows a fine, diffuse pinkness of the conjunctiva, which is easily mistaken for the ciliary infection of iris (iritis), but there are usually corroborative signs on microscopy, particularly numerous lymphoid follicles on the tarsal conjunctiva, and sometimes a punctate keratitis.

Pancreatic diseases that affect digestion refers to disorders affecting the exocrine pancreas, which is a part of the pancreas involved in digestion.

One of the most common conditions of the exocrine pancreas is acute pancreatitis, which in the majority of cases relates to gallstones that have impacted in the pancreatic part of the biliary tree, or due to acute or chronic alcohol abuse or as a side-effect of ERCP. Other forms of pancreatitis include chronic and hereditary forms. Chronic pancreatitis may predispose to pancreatic cancer and is strongly linked to alcohol use. Other rarer diseases affecting the pancreas may include pancreatic pseudocysts, exocrine pancreatic insufficiency, and pancreatic fistulas.

Pancreatic disease may present with or without symptoms. When symptoms occur, such as in acute pancreatitis, a person may suffer from acute-onset, severe mid-abdominal pain, nausea and vomiting. In severe cases, pancreatitis may lead to rapid blood loss and systemic inflammatory response syndrome. When the pancreas is unable to secrete digestive enzymes, such as with a pancreatic cancer occluding the pancreatic duct, result in jaundice. Pancreatic disease might be investigated using abdominal x-rays, MRCP or ERCP, CT scans, and through blood tests such as measurement of the amylase and lipase enzymes.

Diseases affecting the rectum and anus are extremely common, especially in older adults. Hemorrhoids, vascular outpouchings of skin, are very common, as is pruritus ani, referring to anal itchiness. Other conditions, such as anal cancer may be associated with ulcerative colitis or with sexually transmitted infections such as HIV. Inflammation of the rectum is known as proctitis, one cause of which is radiation damage associated with radiotherapy to other sites such as the prostate. Faecal incontinence can result from mechanical and neurological problems, and when associated with a lack of voluntary voiding ability is described as encopresis. Pain on passing stool may result from anal abscesses, small inflamed nodules, anal fissures, and anal fistulas.

Rectal and anal disease may be asymptomatic, or may present with pain when passing stools, fresh blood in stool, a feeling of incomplete emptying, or pencil-thin stools. In addition to regular tests, medical tests used to investigate the anus and rectum include the digital rectal exam and proctoscopy.
