"Although styes are harmless in most cases and complications are very rare, styes often recur. They do not cause intraocular damage, meaning they do not affect the eye. Styes normally heal on their own by rupturing within a few days to a week causing the relief of symptoms, but if it does not improve or it worsens within two weeks, a doctor's opinion should be sought. Few people require surgery as part of stye treatment. With adequate treatment, styes tend to heal quickly and without complications. The prognosis is better if one does not attempt to squeeze or puncture the"
"Stye A stye, also known as a hordeolum, is a bacterial infection of an oil gland in the eyelid. This results in a red tender bump at the edge of the eyelid. The outside or the inside of the eyelid can be affected. The cause of a stye is usually a bacterial infection by ""Staphylococcus aureus"". The internal ones are due to infection of the meibomian gland while the external ones are due to an infection of the gland of Zeis. A chalazion on the other hand is a blocked oil gland without infection. They are typically in the middle"

"Soft tissue injury A soft tissue injury (STI) is the damage of muscles, ligaments and tendons throughout the body. Common soft tissue injuries usually occur from a sprain, strain, a one off blow resulting in a contusion or overuse of a particular part of the body. Soft tissue injuries can result in pain, swelling, bruising and loss of function. A sprain is a type of acute injury which results from the stretching or tearing of a ligament. Depending on the severity of the sprain, the movement on the joint can be compromised since ligaments aid in the stability and support"

Boils may appear on the buttocks or near the anus, the back, the neck, the stomach, the chest, the arms or legs, or even in the ear canal. Boils may also appear around the eye, where they are called styes. A boil on the gum is called intraoral dental sinus, or more commonly, a gumboil. The most common complications of boils are scarring and infection or abscess of the skin, spinal cord, brain, kidneys, or other organs. Infections may also spread to the bloodstream (bacteremia) and become life-threatening."

Many of the signs and symptoms of Lyme disease are a consequence of the immune response to the spirochete in those tissues. ""B. burgdorferi"" is injected into the skin by the bite of an infected ""Ixodes"" tick. Tick saliva, which accompanies the spirochete into the skin during the feeding process, contains substances that disrupt the immune response at the site of the bite. This provides a protective environment where the spirochete can establish infection. The spirochetes multiply and migrate outward within the dermis. The host inflammatory response to the bacteria"

Sometimes the removed stye is sent for a histopathological examination to investigate possibility of skin cancer. A 2017 Cochrane review found low-certainty evidence that acupuncture helps in hordeolum compared with antibiotics or warm compresses. There was also low-certainty evidence that acupuncture plus usual treatment may increase the chance of hordeolum getting better, though they could not rule out placebo or observer effect, since the studies reviewed either had no positive control, were not blinded, or both."

This group of amoebae is known as a cyst, which is then passed out of the person's body in the feces and can survive outside the body. If hygiene standards are poor — for example, if the person does not dispose of the feces hygienically — then it can contaminate the surroundings, such as nearby food and water. If another person then eats or drinks food or water that has been contaminated with feces containing the cyst, that person will also become infected with the"

Spinal cord injuries can be caused by trauma to the spinal column (stretching, bruising, applying pressure, severing, laceration, etc.). The vertebral bones or intervertebral disks can shatter, causing the spinal cord to be punctured by a sharp fragment of bone. Usually, victims of spinal cord injuries will suffer loss of feeling in certain parts of their body. In milder cases, a victim might only suffer loss of hand"
"Sternum The sternum or breastbone is a long flat bone located in the center of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process. The word ""sternum"" originates from the Greek στέρνον, meaning ""chest"". The sternum is a long, flat bone, forming the middle portion of the front of"

Symptomatic GI involvement occurs in less than 1% of persons (note that this is if one excludes the liver), and most commonly the stomach is affected, although the small or large intestine may also be affected in a small portion of cases. Studies at autopsy have revealed GI involvement in less than 10% of people. These cases would likely mimic Crohn's disease, which is a more commonly intestine-affecting granulomatous disease.

The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain. In humans and other hominids, the thorax is the chest region of the"
"Side stitch Side stitch (also called a side ache, a side cramp, a side crampie, a side sticker or simply the stitch) is an intense stabbing pain under the lower edge of the ribcage that occurs while exercising. It is also referred to as exercise-related transient abdominal pain (ETAP). Some people think that this abdominal pain may be caused by the internal organs (like the liver and stomach) pulling downwards on the diaphragm, but that hypothesis is inconsistent with its frequent occurrence during swimming, which involves almost no downward force on these organs. If the pain is present only when"

In addition, if the cysts were to rupture while in the body, whether during surgical extraction of the cysts or by trauma to the body, the patient would most likely go into anaphylactic shock and suffer from high fever, pruritus (itching), edema (swelling) of the lips and eyelids, dyspnea, stridor and rhinorrhea. Unlike intermediate hosts, definitive hosts are usually not hurt very much by the infection. Sometimes, a lack of certain vitamins and minerals can be caused in the host by"

In some individuals, portions of the duct remain behind, leaving small pockets, known as cysts. During a person's life, these cyst pockets can fill with fluids and mucus, enlarging when infected, presenting the thyroglossal cyst. The thyroglossal tract arises from the foramen cecum at the junction of the anterior two-thirds and posterior one-third of the tongue. Any part of the tract can persist, causing a sinus, fistula or cyst. Most fistulae are acquired following rupture"
"lice typically are found attached to hair in the pubic area but sometimes are found on coarse hair elsewhere on the body (for example, eyebrows, eyelashes, beard, mustache, chest, armpits, etc.). Pubic lice infestations (pthiriasis) are spread through direct contact with someone who is infested with the louse. Some STIs can also be contracted by using IV drug needles after their use by an infected person, as well as through childbirth or breastfeeding. Typically, older men and women maintaining interest in sexual interest and activity could be therapeutic; it is a way of expressing their love and care for one"
"Stingray injury Stingray injuries are caused by the venomous tail spines, stingers or dermal denticles of rays in the order Myliobatiformes, most significantly those belonging to the families Dasyatidae, Urotrygonidae, Urolophidae, and Potamotrygonidae. Stingrays generally do not attack aggressively or even actively defend themselves. When threatened, their primary reaction is to swim away. However, when attacked by predators or stepped on, the stinger in their tail is whipped up. This is normally ineffective against sharks, their main predator. Depending on the size of the stingray, humans are usually stung in the lower limb region. Stings usually occur when swimmers or"

"individual may experience headaches, seizures, vomiting, paralysis affecting one side of the body (hemiplegia), paralysis involving one limb (monoplegia), and loss of ability to coordinate muscles and muscle movements. Many of these symptoms are due to the buildup of inter-cranial pressure from the growing cyst or from the cyst pressing on other parts of brain. When the cyst occurs in the spinal cord, it can cause severe pain and inflammation, and loss of feeling in some nerves. When the cyst occurs in the eyes, it causes decreased vision and headaches. In the muscular and subcutaneous tissues, the cyst causes disfiguring"

"Body-stalk The body-stalk, also known as the allantoic stalk, is a band of mesoderm that connects the caudal end of the embryo to the chorion in development. With the formation of the caudal fold, the body-stalk assumes a ventral position; a diverticulum of the yolk-sac extends into the tail fold and is termed the hindgut. With continued development, the body-stalk is later replaced by the umbilical cord. Body stalk anomalies occur in approximately 1 in 15,000 births. They are due to defects in the formation of cephalic, caudal, and lateral embryonic body folds, that result in a reduced or absent"
"Testicular trauma Testicular trauma is an injury to one or both testicles. Types of injuries include blunt, penetrating and degloving. Because the testes are located within the scrotum, which hangs outside of the body, they do not have the protection of muscles and bones. This makes it easier for the testes to be struck, hit, kicked or crushed, which occurs most often during contact sports. Testicles can be protected by wearing athletic cups during sports. Trauma to the testes can cause severe pain, bruising, swelling, and/or in severe cases even infertility. In most cases, the testes—which are made of a"

The stirrup-shaped small bone is on and transmits these to the oval window, medially. The stapes is the smallest and lightest named bone in the human body, and is so-called because of its resemblance to a stirrup (). The stapes is the third bone of the three ossicles in the middle ear. The stapes is a stirrup-shaped bone, and the smallest in the human body. It rests on the oval"

All people with chronic pain should be tested for gonorrhea and chlamydia. Ultrasound is useful if the cause is not certain based on the above measures. If the diagnosis of torsion is certain, imaging should not delay definitive management such as physical maneuvers and surgery.

The scrotum lymph drains initially into the superficial inguinal lymph nodes, this then drains into the deep inguinal lymph nodes. The deep inguinal lymph nodes drain into the common iliac which ultimately releases lymph into the cisterna chyli.

A small SCT, if it is entirely inside the body, may not present for years, until it grows large enough to cause pain, constipation and other symptoms of a large mass inside the pelvis, or until it begins to extend out of the pelvis. Even a relatively large SCT may be missed, if it is internal, because the bony pelvis conceals and protects it."

Such examples include a baby who has not had its diapers changed often or an incontinent elderly person who has not been helped in maintaining routine bodily hygiene. Flies lay their eggs in and around clothing and skin which, if left undiscovered, will hatch into maggots (larvae) which begin feeding upon flesh, open wounds, ulcers, and any natural bodily entry point. Over time, the flesh will be eaten away, and the region may be further infected by bacteria or invaded by other insects. This is known as myiasis. There are two"
"Scrotal septum The septum of the scrotum is a vertical layer of fibrous tissue that divides the two compartments of the scrotum. It consists of flexible connective tissue. Its structure extends to the skin surface of the scrotum as the scrotal raphe. It is an incomplete wall of connective tissue and nonstriated muscle (dartos fascia) dividing the scrotum into two sacs, each containing a testis. Histological septa are seen throughout most tissues of the body, particularly where they are needed to stiffen soft cellular tissue, and they also provide planes of ingress for small blood vessels. Because the dense collagen"
"Bursitis Bursitis is the inflammation of one or more bursae (small sacs) of synovial fluid in the body. They are lined with a synovial membrane that secretes a lubricating synovial fluid. There are more than 150 bursae in the human body. The bursae rest at the points where internal functionaries, such as muscles and tendons, slide across bone. Healthy bursae create a smooth, almost frictionless functional gliding surface making normal movement painless. When bursitis occurs, however, movement relying on the inflamed bursa becomes difficult and painful. Moreover, movement of tendons and muscles over the inflamed bursa aggravates its inflammation, perpetuating"
"Scleroderma Scleroderma is a group of autoimmune diseases that may result in changes to the skin, blood vessels, muscles, and internal organs. The disease can be either localized to the skin or involve other organs in addition to the skin. Symptoms may include areas of thickened skin, stiffness, feeling tired, and poor blood flow to the fingers or toes with cold exposure. One form of the condition, known as CREST syndrome, classically results in calcium deposits, Raynaud's syndrome, esophageal problems, thickening of the skin of the fingers and toes, and areas of small dilated blood vessels. The cause is unknown;"
"A stroke usually affects only one side of the body; loss of sensation due to a stroke will be lateralized to the right or the left side of the body. The only exceptions to this rule are certain spinal-cord lesions and the medullary syndromes, of which Wallenberg syndrome is the best-known example. In this syndrome, a stroke causes a loss of pain-temperature sensation from one side of the face and the other side of the body. This is explained by the anatomy of the brainstem. In the medulla, the ascending spinothalamic tract (which carries pain-temperature information from the opposite side"

Upon awakening, application of a warm washcloth to the eyelids for one to two minutes may be beneficial in decreasing the occurrence of styes by liquefying the contents of the oil glands of the eyelid and thereby preventing blockage. To prevent developing styes, it is recommended to never share cosmetics or cosmetic eye tools with other people. People should also keep their eye tools clean and generally practice proper eye hygiene. It is also recommended to remove makeup every night before going to sleep and discard old or contaminated eye makeup. Most cases of styes"
