I started taking CBD oil for chronic back pain, and have found that it does help with my headaches. It does not seem to help as much as my prescription migraine medication once a headach has started. However if I am regularly taking the CBD oil drops for my pain then the migraines seem to be less frequent. (When I take the CBD oil drops I do not have to take as much narcotic pain meds which could be a cause of some of my headaches). Over all I would recommend trying them. I have never heard of anyone having a bad side effect.
Sorry this is so long I hope it helps! 😁

I also have been taking Topomax for the past 6 weeks now and have worked up to 100mg. . I have massage therapy and chiropractic treatment once a month. They are both life savers and keep me going.

I take Magnesiun/calcium, co q10, Omega , D, B complex all recommended by my doctor.

Magnesium @400 2x a day is what I have been told to take. On top of making sure you have enough potassium. Check vitamin d levels. I take 13,000 every day. Also topamax can help with migraines. I haven't had much luck with everything they put me on but I have been seeing a chiropractor and have only had 2 headaches in 3 weeks.
