@Davsey27 -- I no longer have Kaiser, but I know that their head of medicine for Northern CA changed course on ME/CFS about a year and a half ago--he decided it might actually be a thing and thusly, that the physicians under his supervision ought to respond in some constructive way to it. I think there was some increased training for staff and a decision to stop automatically dismissing patients who walked in with all the diagnostic criteria for CFS.
Someone else here might have more recent Kaiser NoCal experience here than I. Mine ended prior to this shift in policy so all I ever got from them were bored sighs and barely concealed rolls of the eye. I know you don't have Kaiser, but it can be cheaper than other insurance, and I believe (you'd have to check) there is a Medicaid option to choose them.
I have had almost no luck, like most of us, with a long string of doctors, some of them expensive, some not so much. I think I mentioned in a PM that I did get diagnosed by Anas Hana in Berkeley. I didn't get much treatment, but I did go to him with a carefully laid out list of symptoms and timing along with Fukuda, International and IOM criteria and he agreed that yes, it looked like there was match.
So...I think you might want more than a diagnosis? It is a wonderful place to get to--such joy to finally have it named and honored in some small way--but then what?
I hope someone here has a name in their pocket to share with you. In the meantime, I kinda wish I was in Mexico!
