Tingling in the fingers - Definition


Definition


Tingling in the fingers is an uncomfortable sensation of variable duration, affecting the fingers of one or both hands: the corresponding medical term is "paresthesia." The motor function of the fingers is not affected, but the sensitivity is changed, in connection with a nervous origin. These symptoms may be side effects of a nerve injury in the arm, or even of a compression of its root as part of a hernia located near the cervical vertebrae. Frequently, there is a compression of the median nerve by swelling in the wrist, the carpal tunnel. Medications or neurological diseases may also be responsible.
