Question: I recently had knee-replacement surgery and now my feet often hurt or feel like they are burning. Could the surgery be the cause?
Dr. Hibberd's answer:
Knee-replacement surgery will rarely cause such symptoms. But burning feet can be a sign of endocrine disease (such as diabetes), arterial disease, neurological or nerve disorders. Auto-immune diseases, cancer, infections, vitamin deficiencies, and exposure to a toxic substance can also produce such pain.
I'd recommend a visit to your doctor for a more complete physical examination.
