Hi there

Sounds like you are doing everything you can to stay on top, work through pain, move, and avoid meds that make you feel badly. It is hard if you have a sensitive body to take these meds. I am in same situation. Many meds make me too sick to take. We all have to find our own balance.

It can be hard to be treated by these doctors if when we go in, the first things they suggest, and many after, are things we can't take or refuse to take. It sets up the stage for a tougher doc/patient relationship. I have lived this. I would consider asking for alternative treatments which mainstream docs may not do and checking out something called: Low Dose Naltrexone. It is not a regular drug like neurontin or lyrica etc, it is something they compound in pharmacy with little to no side effects at all. It has helped some people with RSD.

I tried it with no results but also ZERO side effects, I mean zero and I am sensitive. Also some people take a lot of Vit C and some take something called NAC, and it can't hurt to take magnesium etc. As for docs taking you seriously, it is hard when you can't take many meds, they have a tough time working with that I have found. If they suggest things, try and stay open minded or approach it with..."I can't take that class of drugs, do you have anything else that might produce less side effects for my system/body.." I want to get well and reduce pain, are their topicals or other things you might suggest...." Etc. Topicals are much less harsh...since we are not ingesting them.

Good good luck and stay positive, it's a great way to approach this.
They do compound pain creams and gels, maybe you can get one with ketamine, lidocaine and things like gabapentin. WHen it is blended in a cream and on the skin, it can help. Without knocking you out!
