Sounds like i am in the same boat as many of you are. On Oct 7 2017 I got a flu shot for the first time ever. I am 65 and in pretty good health. About 2 weeks later I noticed a pain developing in my right hip, it progressively got worse and then moved to my groin area. I thought I had a dislocated hip so I went to a chiropractor. He took x-rays and said all my muscles where all jammed up on that side. I had muscle stimulation with no relief. The pain slowly moved to the other side of my hip and groin area,( that was about 2 months after my shot). The pain slowly left my hips(but left stiffness behind), and went to my left shoulder. I wasn't even able to put my socks or a shirt on without very much pain. Now it seems to be in my front shoulder-neck area. This has been 3 1/2 months now and I am still have trouble even getting out of bed and am very stiff in the mornings. My Dr. is finally going to do blood work tomorrow, and I hope he is able to help me as I am not sleeping normal and am having a very hard time even walking or sitting. Ibuprofen has helped but pretty much nothing else. There should be a class action lawsuit against the drug co distributing this poison. I WILL NEVER get or recommend a flu shot to me or anyone else. So sorry to hear of all the trouble this is giving so many people.
