Hello Karen,
Welcome to the NeuroTalk Support Groups.
I'm very sorry to read about your accident. It sounds really bad.
I see you have already posted in the middle of a thread in the PN forum and it may have been overlooked somewhat so it may be better to start your own thread there so that others won't miss your post and questions.
Peripheral Neuropathy Forum
There is also the
PN Tips, Resources, Supplements & Other Treatments SubForum
That contains information about supplements, medications and other treatments that may be helpful to read. I'm sure the members here will offer you information and support to aid your recovery and to help you deal with the pain that you're experiencing.
take care.
