3 years of medical tests and still no answers

I think a neurologist is best there. Though headaches unfortunately can be hormonal and caused by many other factors 😒 mine are stress, hormonal, and probably dietary and blood related. I get frequent awful headaches around my period because of the spike and fall of estrogen. I think blood sugar can play a role too since you can get them when you dont eat. My mri came out normal too i just get migraines and bad headaches every once in a while.. its just something I have to maintain.
