What is painful diabetic neuropathy?
There are many types of diabetic neuropathies (nerve disorders caused by diabetes). Peripheral diabetic neuropathy causes pain, weakness, and reduced or lost sensation in the feet. Some people may develop tingling, burning, or numbness; others may experience sharp pains, cramps, and extreme sensitivity to touch. Other types of diabetic neuropathy affect other parts of the nervous system and may affect digestion, balance, vision, and many other bodily functions.
