I have been suffering with chronic headaches and migraines for the last 15 years. I think I have tried most of the options available to me and am currently doing the Emgality shot which make my headaches more controllable but they’re still there almost every afternoon. I just read an article about VNS or vagus nerve stimulation helping chronic headaches and migraines. (AARP newsletter). Has anyone tried this? Apparently it is FDA approved to reduce inflammation. Feedback would be most welcome.
