For the last week I have had sharp pain in my left wrist. It hurts more and more. If I don't use it at all it seems to just ache, but any time I move it or try to lift anything with that hand it hurts really bad. I have been using a wrist splint but it hurts really bad to wear it. I also have been applying ice and elevating my wrist. I also have beent aking mortin to help relieve the pain but it seems to just take the edge off. I work as a nurse aide and I am still working but having a hard time performing my job due to my wrist. When the pain first started it was sudden I did not injure it by falling that I know of, but could have injured it at work. I do not have any health insurance right now and would only like to go to the ER as a last resort. Any suggestions on what could be going on or if I should go to the ER?
