Bruise on tail bone, pain on sitting, walking, back pain. Family history of ankylosing spondylitis. Treatment?
I have an unexplained bruise on tail bone and it hurts to sit and walk, I also have a lot of lower back pain that has been a problem since I was a child. My mother has Ankylosing spondylitis and I have a lot of symptoms that she has but I have been tested for it a few years ago and it came back negative. Could that have been an error and I have it to?
