Numb right foot, tingling and cold. what are these symptoms of?

Any # of things: Those signs and symptoms by themselves are fairly nonspecific. Even when when they occur together they do not point to a single diagnosis. If your pmd cannot treat this i would suggest that you be seen by an orthopedic foot and ankle surgeon. One in your area can be found at www.Aofas.Org.

Neuropathy: Is the most likely resaon but they are many different causes of neuropathy. Can also be a vascular condition. See a podiatrist.
