Numbness in Arm/Leg

Sometimes called a neuropathy, symptoms of numbness and/or tingling in an extremity are a serious problem.  This symptom indicates a loss of nerve function and, in some cases, blood flow, to the arm or leg. Prolonged periods of numbness will lead to muscle weakness and permanent damage.  Spinal misalignments and disc problems are primary causes for numbness in an arm or leg.
