I’ve had them for nearly 30 years. They thought at the time that years of chronic sinus infections, then three consecutive sinus surgeries, caused the nerves to become “irritated” for lack of a better word and then not know how to turn off. I’ve been everywhere, been on every drug, had every procedure. It’s been a lifelong battle, all while raising two kids and having a demanding career. They thought stress a trigger, so I left my job 11 yes ago. No help. Right now I take Nurtec every other day. I have a number of drugs to use as abortives. Nurtec is best I’ve found for me. It’s an every day struggle along with the gi issues which of course they say is a gut-brain thing because I also have slow-motility. Don’t know if any of this helps. Best advice. Headache specialist. All neurologists are not headache specialists.
