I agree with MominPain. Go for the blocks. They may do what you want them to without going through the ketamine since at this point it is only in you hand and wrist. The blocks do work for a lot of people.

Have you tried the lidocaine patch. I wrapped them around my hand a lot of times at night. I used a heating pad to make them work faster. I couldn't do the fentenal patch.

I too am amazed at how well you are doing with your schooling. You are a very strong person to accomplish what you are doing with the RSD pain.

I hope that you can soon get it back into remission.
