Hypoesthesia or numbness is a common side effect of various medical conditions that manifests as a reduced sense of touch or sensation, or a partial loss of sensitivity to sensory stimuli. In everyday speech this is generally referred to as numbness.
Dysesthesia is an unpleasant, abnormal sense of touch. Its etymology comes from the Greek word "dys," meaning "bad," and "aesthesis," which means "sensation" (abnormal sensation). It often presents as pain [1] but may also present as an inappropriate, but not discomforting, sensation.
Paresthesias are usually painless and can occur anywhere on the body, but most commonly occur in the arms and legs. [1] The most familiar kind of paresthesia is the sensation known as "pins and needles" after having a limb "fall asleep". A less well-known and uncommon paresthesia is formication, the sensation of insects crawling on the skin.
[3] [8] [5] [2] [6] [4] (The term "meralgia paraesthetica" combines four Greek roots to mean "thigh pain with abnormal sensations".) Examples of paresthesias (abnormal sensations but not unpleasant) and dysthesias (abnormal sensations that are unpleasant) are burning, tingling, numbness, stinging, hypersensitivity, and itching.
Small fiber neuropathy is considered a form of peripheral neuropathy because it affects the peripheral nervous system, which connects the brain and spinal cord to muscles and to cells that detect sensations such as touch, smell, and pain. Insensitivity to pain can be particularly problematic.
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
