I have also been lucky enough to have been seen by Doctors at the MAYO Clinic in Jacksonville, FL who have prescribed a mass of medicines to take in rotation to help with the pain. Such as Tramadol, Gabapentin
Topiramate with vitamin B,D, iron, and IBUPROFEN. However, the only true substance I have found that kills the pain is cocaine. Again, I am not joking! But, I am not one to break the law or advocate its use.
I give you this info.
