I just had surgery 2 weeks ago and I've had no problems. I think it is just going to depend on how your body responds to the stress of the surgery. After my surgery in April, I develop pnemonia, had extensive lower back and joint pain. I think the problem was that I had been fighting bronchitis for a few weeks prior to the surgery and then the surgery just stressed my body out. If you decide to go forward with the surgery make sure you are healthy to begin with.
