I was diagnosed with AS when I was 44 . I kept complaining to my doctor about all the pain I was in over the years. I had pain in my knees, then in my elbows and my hip, I injured my back when I was 17 so my back has always hurt . I now have pain in my neck, shoulders and arms which is caused from a pinched nerve. I found out I had AS when my right side, hip area was very painful and they did a x-ray and found that my SI joints were inflamed. I just want anyone who has chronic pain in their back which gets better when your up moving around and is worst in the morning and at night with a lot of stiffness to be aware that it could be AS. With women it may start in your neck. It took the doctors over 15 years to diagnose me with AS. At fist they thought I had fibromyalgia because I hurt all over. I was reading some of posts and it sounds like some of you may have AS and I don't want you to suffer in pain anymore.
