It sounds like you have a lot of issues going on and if I were in your position I would try to find a common link AFTER listing out all your symptoms, even the ones that already been accounted for as one already diagnosed problem or another. Do that BEFORE you see your doc this week and present what you have to them.

Try to find "one good doctor" to try to piece the symptoms together and then investigate like hell for any kinds of tests that might lead to a common problem. Finding a doc like that is not easy in these times. Specialists for instance, will blow right past anything that is not "their specialty". A good doc will ask questions and require tests, not proclaim some disease upon your few meetings. Encourage them to dig for the problem.

I hate to say it like this but as the patient in today's health care you HAVE to investigate and advocate for yourself and you must firmly demand better care if you feel like you're not being seriously considered. This problem will likely not be found in any single 15 minute office meeting.

BTW, I would also advocate for some vitamin tests (B absorption especially) and detailed blood tests in addition to the hormones suggested above. This is your one chance to guide the accurateness of your outcome.

I am also sitting in the precipice of a diagnosis. Understand what a diagnosis will and will not do for you. Do not let a doc jump to conclusions and show you the door. There isn't much of a treatment available for PD so keep that as the last option when all else is ruled out.

Best of luck ..
