Welcome to NeuroTalk:

We here have alot to read and learn. The reason for this is that doctors don't always know what to do with PNers. So we have searched the net, and provided the most recent medical information for readers here to try on their own (with some medical support and testing) to heal themselves. Sometimes you can do simple things, to allow yourself some relief. But you have to do that homework. Do a little bit each day... many of our members and readers do find some relief. And I do make sure most of it is affordable.

If you read along, you may find someone with something that strikes a familiar chord with you. Also our SubForum has information about toxins, drugs that may cause PN, and other ideas.

The very first thing since you are so tired, is to consider B12 supplements. If you can get tested first that would be ideal.
If not, you can do this yourself for very little money.
