Tina,
I just found out that I have a hip injury so I wrote to my mast cell specialist, Dr Afrin, to ask questions regarding the involvement of mast cells in this. I would forward his reply to you but it is password protected. I am going to start a new thread under General Discussions so all can learn from it. Although he doesn't specifically mention subluxations I do believe it falls into the same category. I hope it helps.

Kim
