Hypoesthesia

Decompression sickness Decompression sickness occurs during rapid ascent, spanning 20 or more feet (typically from underwater). Decompression sickness may express itself in a variety of ways, including hypoesthesia. Hypoesthesia results because of air bubbles that form in blood, which prevents oxygenation of downstream tissue. Similarly to the trigeminal schwanonoma mentioned above, this can result in facial hypoesthesia. Rhombencephalitis may also result in hypoesthesia of the V1 through V3 dermatomes. such as ampicillin, to remove the bacteria. Intradural extramedullary tuberculoma of the spinal cord (IETSC) IETSC is a cancer of the spinal cord that involves hypoesthesia of all parts of the body associated with the affected spinal nerves. The inability to convey information from the body to the central nervous system will cause a total lack of feeling in the associated regions. Cutaneous sensory disorder Hypoesthesia is one of the negative sensory symptoms associated with cutaneous sensory disorder (CSD). In this condition, patients have abnormal disagreeable skin sensations that can be due to increased nervous system activity (stinging, itching or burning) or decreased nervous system activity (numbness or hypoesthesia). Beriberi Hypoesthesia originating in (and extending centrally from) the feet, fingers, navel, and/or lips is one of the common symptoms of beriberi, which is a set of symptoms caused by thiamine deficiency. == Diagnosis ==

A patient experiencing symptoms of hypoesthesia is often asked a series of questions to pinpoint the location and severity of the sensory disruption. A physical examination may follow where a doctor may tap lightly on the skin to determine how much feeling is present. Depending upon the location of the symptoms occurring, a doctor may recommend some tests to determine the overlying cause of the hypoesthesia. These tests include imaging computerized axial tomography (CT) and magnetic resonance imaging (MRI) scans, nerve conduction studies to measure electrical impulses passing through the nerves in search of damage to the nerves, and various reflex tests. An example of a reflex test would be the patellar reflex test. ==Treatment==

Treatment of hypoesthesia are aimed at targeting the more broad disease or illnesses that has caused the side effect of sensation loss. == See also ==
