Another failed trip to the ER

Again, after a long night of pain, pain in which I suffered for a whole week, the inability to move or use my right arm and hand, the ER doctor says, "I don’t know what is wrong?" "Here is a prescription for percocets for the pain and follow up with your PCP." How many of you go through this? Why must we go though this? I spent practically a whole day in the ER just to be given a prescription. Wow!
