Can vitamin D treat pain?

Women with dysmenorrhea who take a single high dose of vitamin D suffer much less menstrual pain and have no need of pain medications for any reason for up to 2 months says Antonino Lasco, MD, from the Department of Internal Medicine, University of Messina, Italy. One should use cholecalciferol in these patients, especially when exhibiting low plasmatic levels of 25(OH)D (25–hydroxyvitamin D). The study is published February 27 in the Archives of Internal Medicine.
