The role of vitamin D in the treatment of nerve pain in diabetes

This study is testing whether taking vitamin D supplements can reduce nerve pain in the feet in people with type 2 diabetes. Many people with type 2 diabetes develop a condition called diabetic neuropathy, which causes burning, tingling, or stabbing pain — usually in the feet. Vitamin D deficiency is common in people with diabetes, and researchers believe correcting this deficiency may help ease nerve pain.
