I pull charts at my job and my wrist has this bad pain. is this open wrist and what should i do??

See your physician: Did you physically injure your arm/wrist in some way? There are many reasons, but it all depends on your medical history and recent history. See your physician to discuss the symptoms in detail and to undergo a physical examination. If indicated, you may be referred to a neurologist. http://www.nlm.nih.gov/medlineplus/arminjuriesanddisorders.html
