Welcome to HW forums...I think you'll find it an understanding and helpful group.
I don't have any of the issues you're describing, but it sounds like you have a pretty good doctor there. Is he recommending the surgery now, or are there other alternatives you can try instead? If he's leaning towards surgery, I would get a second opinion, just to be sure as it sounds like there's a lot of stuff happening in your body.
Other questions I would be asking would include whether you would get significant pain relief after surgery or just moderate, how long you would have to be in hospital and how long would it take for you to heal completely. How long would you be doing rehab afterwards (or would there be any after surgery treatment needed).
It sounds like the doctor is offering you a pretty good chance of feeling much better after the surgery, but if that means more surgery every 3 years then you have to weigh that against living like you are for the next 1, 4, 8, 20 years, etc. Personally, if I were in your shoes and had to make this choice, I would go for the surgery.
I hope things work out well for you. Please keep posting so we know how you're doing.
