I have pain in my right arm starting from my wrist to halfway up my arm. it's a sharp pain and basically comes when i move my arm. any suggestions as to what it possibly cd be? thank you.

Pinched nerve: Is very likely and it could be coming from your neck, your shoulder, or other places. Try heat, avoid movements that cause the pain, Tylenol, topical nonsteroidal like Diclofenac. You may need to see someone to get this diagnosed and have some x-rays to see if it might be bone doing the pinching. If you get weakness or numbness it's more urgent. Good luck to you, be safe but take care.
