I agree with @ Blazer95. I've been the victim of multiple diagnoses for years now. One right after the other.
OK, my fine and caring neurologist died 4 mos. ago. I still miss him, but I did find a replacement. Not great the first visit, but on my second we established a cordial relationship. Most doctors won't order expensive tests until a patient shows an extended need for one.
I just had my third visit with my cardiologist. The first two...rather blotto, although he carefully reviewed my chart and found it hard to put all of my problems together (how to treat them). Actually, he reviewed the chart before he came in for the appointment. This last visit, the 3rd was totally different. We were even joking around, he was telling me about his new baby and how much joy he gave him and actually brought up cutting down on the number of visits I had to attend. This man is going to be kind and good, he cares.
Other doctors I knew from the beginning would not be in the league of a good patient/doctor relationship. So I would suggest that if someone is half decent, give them three chances and then move on.
I don't expect a doctor to cure me, but I do expect respect and kindness and of course I give it in return. Besides, if my original neurologist hadn't been the man he was, I wouldn't have been in trials for experimental drugs (which helped with a lot of pain...not opiates), anxiety and other matters. I wasn't the only one he was kind to....he was like that with all of his patients. Caring, joking, a visit was almost a pleasure.
So good luck to everyone. You should ask for MRI's after you've been going awhile, but most will want them after the 2nd or 3rd visit. Believe it or not, new things are being discovered each day....I should know, I've lived with this for way over 35 years, probably closer to 40. Progress has been made and eventually you and your doctor will trust each other enough to have a relationship of patient/doctor. A true one. Yours, Lenora
