Hi ~ It sounds like you're a barometer like I am. Whenever the barometric pressure changes, I'm in agony!
Your doctor SHOULD have informed you that pain is NOT a reason to have surgery, and he should NOT have predicted how much pain relief you'd get. Surgery ONLY corrects mechanical problems -- it many times does not ease pain. Many times you end up with the same pain or worse -- so any doctor who says he can relieve your pain is WRONG.
I'm sorry you're having such trouble with your doc -- I think we've all been thru this before. If you think that your doctor isn't treating you as he should, I'd find another doctor! You need one who will adequately treat your pain/condition and won't ignore your calls for help. I know that finding one isn't always easy -- many of us have had to see numerous doctors before finding one that cares.
Best of luck & God Bless! Hugs, Lee
