Have you seen a neurologist? Mine subscribed Gabapentin for me. This helps so much. Temperature is a factor in how you feel also. I have to keep my legs warm. Maybe this will help for you also. Warm Epson salt baths can help also. What ever you do, see a neurologist. Hope this helps.

I have this on my entire left side. Yep, if you cut me in half, the entire left side...
I take Vimpat and Gralise. I originally took Vimpat alone, but had to start taking Gralise in addition this past Spring.
When I'm hot, sick or tired it does come back. But not anywhere as close as it was before the meds.

I've had pain in my left foot too feels like bone sticking in you I was told it would where off soon ive had the numbness all down left side too my GP prescribed 3 days of steroids which worked a treat but ive been told it could well go numb again, ive got Gabapentin 300 mg too which is good, sorry not much help to you I was diagnosed MS in 1990 hope all goes well for you

I'm allergic to tegretol

Well I did a brownie but smart me ate the whole thing 😱
