When I was a preteen I had migraines all the time, the only thing that helped was a towel full of ice, a dark quiet place, and a half hour alone. I would still have the headache hang over but it would relieve it tremendously.
My mother had a knack for finding whack job doctors, and was put on epilespy medicines that only made things worse, and sleeping pills that would last about two weeks and stop working when I built up a tolerance, hence I stopped all med.s and pasted out alot for a few days but used the tests given to understand it was from stress.
I am also a medic, and suggest that you seek an eeg, electrodes on the head to measure brain activity, just to be on the safe side and rule everything else out. I'm sure today it would be a cat scan or an mri, this was back in the seventies.
I just underwent surgery to fuse to discs in my neck due to lack of bone in the front, from torture forty years ago, it was giving me headaches and I knew that one was physical.
Just relax, you sound like your moving mountains to be uptight to relaxed is excellent, good work.
Hope you get to the bottom of it soon. Keep us posted.
