The symptoms of a pinched nerve include numbness or decreased sensation in the area supplied by the nerve, such as the back; a sharp or burning pain and tingling, itching, prickling and burning sensations, according to Mayo Clinic. Other symptoms are muscle weakness in the area of the nerve compression and frequently feeling that a hand or foot has "fallen asleep."
