Even though my insurance won't cover it, I've found a lot of relief from a Ketamine cream my doctor prescribes. It costs $178 for a month's supply,but the pharmacy is very accommodating and will send smaller (cheaper) quantities upon request. They are located in Alabama, called Total Pain Solutions (TPS). It might be hard to believe a cream could be effective, but it really calms my nerve pain when even Lyrica and pain meds don't and it seems to be helping the dry skin in the areas where my nerves are most damaged. I'm not saying it will work for everyone...but it has been a blessing for me. My best wishes to you in your stuggle to cope with this disease.
