Thanks for all the quick responses. Unfortunately, Epsom Salts do not work for me. So I would not hold out much hope for cream.

The good news is my doctor just got back to me and said he has heard of people compounding Gabapentin and Lidocaine together for topical use. His thought is that the Lidocaine is really what's working in the combination. He wants my pharmacist's contact info at my local compounding pharmacy so they can confer and he wants to research this a bit.

I am excited my doctor is willing to work with me on this. Sounds like we off to the races.
