Welcome to NT
So sorry you're suffering.
There's lots of info here to research about the stimulators and RSD. Loooots of info. Alffe gave you the RSD forum. That's a great start so you can compare your symptoms.
I would like to suggest you keep a dairy right now, with the help of family too. I'm holding out it's something else and not RSD.
Are you sure your procedure itself don't have something to do with your painful state? unintentional and maybe unexplainable, but onset was immediately after it. It's hard to pin some things down if they can't see it on x-ray and can't correct it. I'm assuming the surgeon and doctors are saying this is not a "normal" side effect/risk for the procedure you had.
I've heard mostly good about stimulators. Patients usually know and doctors are specific about the diagnosis and the prognosis. I guess my point is, don't grab at anything, especially invasive, until you're sure. Believe it or not, it could get worse if they don't know for sure. Just be cautious. I hope I don't cause you anxiety I just feel you need to be aware and guard yourself here.
Lawyers see a lot of suffering too, but you need a doctor. Pain management doctors are the trend nowadays to evaluate and treat painwrecked conditions. That's an adventure too, if you're not already there, but thank God for them. They did give me relief. I just never liked my situation, I guess. Just needing pain management says a lot, don't it?
We're here for you. No question is too silly.
