Treatments for diabetic neuropathy (nerve damage caused by high blood sugar levels) include medications such as amitriptyline, duloxetine, or pregabalin to manage nerve pain, along with lifestyle measures like regular exercise, a balanced diet, and strict blood sugar control. Alpha-lipoic acid may help relieve nerve pain and can be taken as a 600 mg tablet, such as Alafin Tablet, but only under your doctor's supervision.
