Is severe feet pain a systemof PAN

In 1993 I was diagnosed with a viscosities disorder called polurateritus. I was treated with a drug called cytoxan and pain medacations. I was on the medications for six months. I was told the mortality rate would be five years, however I am now 52. The pain in my calf’s and lower extremities got some what better but has never gone away. Now my calf pain, feet pain, and bone pain is worse than it has ever been. The only visible signs are red spots on the top of my feet. Any pressure or touching on my calf’s legs and feet cause severe pain. I can tell I am dyeing with each passing day. Are these systems of the Pan coming back and can I be treated?The problem is I can’t find a Doctor that will help me get the test that I require to see what is happening to me now.
