I have nerve damage from a shattered elbow a year and a half ago. I still have numbness and tingling in the outer 1/3 of my arm from elbow to fingers. The elbow was replaced with a replacement joint and a metal rod screwing the arm together (fractured in three places) All was the result of a fall. I haven t had much luck with my doctors- orthopedic and regular primary care dr. Could Botox help the damaged nerves ? Any other treatment ?
