My doctor prescribes me a Ketamine compounded cream that my insurance won't cover. But I pay for it anyways because it does help. A month's supply with application 4 times a day is about $170. The pharmacy is in Alabama called Total Pain Solutions (TPS). They ship it in a day or two from ordering. For me, it's woth it and I can usually make it stretch longer than a month but still get some benefit.

Good luck!
