Wrist has been achy and arm hurts after i fell down onto palm outsretched hand. I went to the doctor and he had me do xrays. The xrays came back with no bone damage or sprain (didnt know you could tell sprain in xray) my hand hurts wrist and arm. I dont understand why. He said it is nerve inflamation because when he touched my elbow it hurt felt weird all the way to fingers. I still dont believe this is the problem what do you think. Also my wrist cracks all the time when i move it and arm feels like someone is squeezing it sometimes i get little sharp pains in wrist but nothing crazy.
