When to seek medical advice
By Mayo Clinic staffSeek medical care if you notice:
- Unusual burning, tingling weakness or pain in your hands or feet
- Dizziness
- Markedly increased or decreased sweating
- Changes in your digestion, urination or sexual function
These symptoms don't always indicate nerve damage, but they may signal other problems that require medical care. In either case, early diagnosis and treatment offer the best chance for controlling symptoms and preventing more-severe problems.
See your doctor immediately if you have a cut or sore on your foot that doesn't seem to be healing, is infected or is getting worse. Even minor sores that don't heal can turn into ulcers. In the most severe cases, untreated foot ulcers may become gangrenous — a condition in which the tissue dies — and require surgery or even amputation of your foot.
