Some potential causes include vitamin deficiency, nerve damage, nerve compression, and alcohol over consumption, side effects of different medications, or as a result of different systemic medical conditions such as diabetes. Get evaluated by a professional to determine the diagnosis. Treatment is based on the diagnosis.
Neuropathy. Contact your doctor or a neurologist immediately. You have diabetic neuropathy which is causing your symptoms and obviously you need help.
