Can you consult with some lawyers, to find out about any possible lawsuit with compensation for stress, RSD & surgery pain & suffering?
The RSD is a biggie.. that can be a lifelong & painful condition.

Sounds like some sort of medical malpractice.. surgeons must make sure they are doing the right thing when they operate on someone.

Proving the RSD happening due to the first surgery might be difficult, but if you were generally healthy and didn't have any treatment for it previously & have some high rated drs agreeing that it is RSD.

I don't know how medical lawsuits are handled in Canada..
