My rheumatologist suggested I try this for the nerve pain I have. She said it takes 3 to 5 weeks to notice a change. So I found this on Amazon. I am taking this twice a day. While it hasn't eliminated the pain it has greatly reduced it.
My pain consisted of feeling like I had walked into a spider web. (for those with migraines this can also be a pre-curser to an onset of migraines. ) I had what felt like an electrical current shooting through my head or down my back. And I get what feels like a electrical current (not the sharp shooting one but just tingly) that runs from neck and travels down left arm.
So I am hoping this continues to help. (so far the only sensation I am still getting is the tingling down arm..)
Here is what medMD has to say about this:
So thought I would share as a simple FYI (for your information)
