question: I recieved a flu shot about 37 hours ago and started having pain in my arm after about 5 hours. It got progressively worse very quickly and ibuprofen and Aleve did not take care of it at all. I have never been in such pain and I delivered 10 babies! I lost the use of that arm in a couple of hours and the pain is affecting my whole shoulder, arm, neck, head, & collar bone. Is this what I must look forward to when I choose to get a flu shot? Will this pain ever go away completely?
