Gotta keep this one brief since I'm on my lunch break. Quick update...
My mom who is a nurse wanted me to try a different avenue other than neurologists since I've seen five with no luck. She recommended seeing an internal medicine doctor or "internist" (not to be confused with "intern"). They're like primary physicians but more in-depth and according to the American College of Physicians (see the link), "they are specially trained to solve puzzling diagnostic problems and can handle severe chronic illnesses and situations where several different illnesses may strike at the same time."
The bad news is, of my migraine friends on Twitter, only one has had luck with an internal medicine doctor. The good news is, someone HAS had luck with one. My desire has always been to find the cause of my headaches to treat them, and I feel that an internist might be the way to go since they cover such a broad spectrum.
Another reason for seeing an internist is I want to get off Lexapro and Lyrica which do not work and I need a doctor to do this. My neurologist will not be happy with me, but I haven't seen her since April and her new facility is still trying to get in United Healthcare's network (my insurance), so there's no telling when I'll be able to see her next.
My appointment is in one week. Wish me luck!
P.S. - When I spoke to appointment scheduler and asked if they handled chronic headaches, she said they'd see me and then refer me to a specialist, but I said been there done that - I want to be treated by an internal medicine doc and find the cause, and then she had me speak to the triage nurse who said she'd have to schedule the appointment first to see what they could do.
