Talk to your doctor about the diazepam. It takes about 6 months after the last dose to feel 'normal' again. It gets much better tho after the first month off. Once this drug is out of your system, then the doctors can accurately assess what is wrong with you.

Diazepam is not a treatment for neuropathy. Withdrawal does cause severe burning pain and many, many other symptoms.

Wishing you well.
