Just out of no where and I say suddenly laying in bed I felt like an electrical shock from my fore arm to my wrist then drove to pick my wife up and all of a sudden from middle of my arm to my wrist really started hurting like a nerve in my wrist then started to swell below my thumb and its more like a lump. It hurts to move and do anything. If I put my arm down it hurts. I have to keep it up next to my chest. Pease tell me what it Could be Thank you.
What do you think it could be
and what will relive the pain
