B-visible,
There is a HUGE difference in yr.s of education & training! A little over 2 yrs schooling & 1yr residency vs. 4 yrs schooling and 3-7 yrs residency, (after college) A PA works under the “supervision” of a doctor, which in reality means, you don’t necessarily ever see the Dr. The PA practices under the doctor’s license. I see a PA for minor stuff like sinus infections, flu, etc. I personally prefer pain management specialists over neurologists but I have never seen a headache specialist per say. I may do so. Regardless, it is always a good idea to be sure they rule out any other conditions as a cause of your headaches. From what I read, in some states a PA cannot order diagnostics (tests, imaging). Good Luck with whomever you see.
