Thankyou! I still have this problem, but would have to have a major surgery to fix it, and I have had back surgery before already for a herniation, so I will wait on that lol! Good luck to you and your sister on finding the cause. It does sound like it's coming from her back. Also, I would hate to see her go through what I went through most of my life, so I would recommend she see an ortho or neuro. They specialize in this and she will get the proper diagnosis and treatment then.
