Paresthesia is a feeling of tingling, burning, pricking, or
numbness of the skin with no apparent physical cause. Some people call it a
feeling of "pins and needles."
Paresthesia that comes and goes (transient paresthesia) is
usually caused by pressure on a nerve, and it disappears gradually as the pressure
is relieved. Other kinds of paresthesia can be chronic and painful and are
often a symptom of underlying nerve damage or disease.
Comparing the affected area with an unaffected area will determine
whether paresthesia is present.
- When the affected area is touched, does the touch
cause the same feeling or sensation as when an unaffected area is
touched?
- Does loss of normal sensation spread beyond the affected
area (usually away from the centre of the body down a limb)?
Treatment for paresthesia depends on what is causing the
problem.
