hi MewsG

Welcome! I am sorry you had to come find us but it is a soft landing place that is great for sharing and support.

I have never encountered any literature that said LSB or SGB was a cure for CRPS. I have read kind of an insane amount of stuff. There have been retrospective studies done and the efficacy rate is not as great as once thought. Blocks of this kind have fallen to lower tier recommendation because of risk and the uncertain response rate. That is not to say that they don't work for some people. Many here have gotten a response that made a difference for them. Others have said they worked a day or two then nothing. Some get no response at all. I would trawl around Pubmed and Google for CRPS and sympathetic blocks and see what comes back. I am on Vacay and using my iPad which is less than ideal for posting links or I'd send you something.

There is a lot of hope for improvement. So ignore the doomsday info and focus on what some of the CRPS bigwigs say which is that 80% of people improve with time. Easy, gentle exercise, keeping the limb moving, reducing swelling, not pushing too hard and causing flare, stress reduction...all these help recovery. Hit the antioxidants. Try something like neurontin or nortriptyline. You can even consider an oral sympathetic blocker. A short course of steroids is useful in the acute stages and even sometimes later. Ketamine infusions are becoming more frequently recommended at early stages and can alter the course of the disease. I am doing a low dose protocol and getting good results. There are many, many options for treatment if you decide that nerve blocks are not for you. Or if you try a couple and don't see the results you'd like. Keep at it, hold on to your recovery like a bulldog. It takes time and persistence and often a lot of trial and error.

I hope you find what works for you soon. Come when you have questions, to share info or just to say hi.

Sending healing love,
