Dear Kevin: Please get more tests, and go to an active center such as Boston, Sloan-Kettering, or Mayo.
Your nerves in your foot can be experiencing neuropathy. Also, specific nerves can just feel discomfort.
My spouse has Amyloidosis and was checked and found to have MGUS. Within six months I took him to Emory were the MGUS turned into an early case of Multiple Myeloma.
His condition is stable now. He used high dose steroids(dex) and thalidomide for his oral chemo. He now only takes the thalidomide. When his counts go up, he will then start a more aggessive chemo.
Check out the Amyloidosis Network site on the net, also check with the Lymphoma Society. Under their umbrella of care they cover, myeloma and amyloidosis. Get the best treatment, and keep yourself healthy.
With regards,
Colleen
