I have been having periodic severe pain in my wrist since I fell ( October 17)and landed on my hand. I have been in a cast since 0ctober 21st. Sometimes the pain is in the form of an excruciating burning pain in the wrist. I am taking hydrocodon 3 times a day. I have no visible swelling , I can move my fingers. BUT there is periodic sharp pain in the wrist and periodic excruciating burning sensation. Is this normal> what should I be doing besides taking the pain pills, resting, moving fingers and arm only when it is bearable?
