I had my flu shot at the local CVS pharmacy the last of October. It is now the 10 of November and my arm still hurts.There is decreased mobility as well as decreased strength. There is somewhat less pain than in the first week but it is not a signifigant difference. I have had a massage, tried Tylenol, Ibuprophere, topical pain potions and wnything else I have been able to think of. The only thing that has given me any relief is Arnica oil, but again that only lasts for several hours. I have had fl shots for years and NEVER had this happen. How much longer is this going to be with me and will it do permanent damage?
