Welcome to the board...there is great knowledge and support here as you can see from Glenn's post.

My heart goes out to you with having to deal with nerve damage and care for a 21 month old...I have a 6 year old and it is a challenge at times but also a wonderful blessing that I try to focus on.

Anyway...I do not know much about CRPS but I found a website that seems to have some great info @ American RSDHope - American RSDHope Organization, How to contact us, You may have already been there but it should help develop some knowledge and questions regarding some of your issues.

But like Glenn said...first make sure of a diagnosis and then find a good therapeutic path forward...find the target first before shooting the arrow.
