Paresthesia is the unpleasant sensation of pins and needles, tingling, or numbness that can be felt in different parts of the body. Paresthesia of the extremities signifies these feelings located in the hands, fingers, feet, and toes. In the majority of cases, this type of paresthesia is caused by nerve disease, such as diabetic neuropathy for example, manifesting as damage of the terminal sections of the longest nerve fibers and typically leading to symptoms in the feet and legs. Paresthesia can also be indicative of nerve pressure, such as in paresthesia of the fingers, a marker of carpal tunnel syndrome where the median nerve is partially compressed in the wrist. There are many other possible causes and pathologies for this condition.
