I am going to the chiropractor for mine which are caused by my C1 vertebra right below my skull being way out of alignment which is pinching nerves. Have you tried chiro for the migraines?
This sounds like something I should do. I had a pinch in c6 for 2~3 years now. Rehabilitation didn’t fix the issue, I was told I probably needed surgery by a few different doctors(including my uncle whom is a doctor of 40+ yr) & I don’t want to do that.
