Karen & CINDY: I was diagnosed 1yr ago. Then told diag. wrong, condition worsened, now told do have ACM, put on steroids and many other meds. Want to know, was told "mild" and would only contribute to my headaches and back pain. Can't be true, then what are all the symptoms I'm having from? Think I'm crazy sometimes, NO HELP. How big does it have to be for them to operate to relieve the pressure? How severe was yours?
