Star, our daughter still struggles with many of the symptoms you are experiencing. She seems to vacillate between Cushing's and Addison's, too. She does have polycystic ovaries, and has had a number of cysts removed ~ some of which had grown onto and into her bladder. (Ouch....) She sees an endocrinologist, and in the past has used metformin with remarkable success. When she needs an anti-diuretic, she is given spironolactone, not lasix. (The spironolactone is a potassium-sparing diuretic which actually helps with some of the other symptoms she experiences.) Metformin is Glucophage. Over time, she stopped the metformin, and her symptoms returned. She has recently been convinced to start the metformin again. We see an amazing change in her on this medication, but she doesn't like to take it. Another recent development was the discovery that her thyroid levels, when examined in depth by a competent specialist, turned out to be all over the map. And then, a tumor was found on her thyroid. It was biopsied, and turned out to be benign.
There is no easy answer for our daughter Star, and there may not be one for you. Our daughter suffered for years through misdiagnosis after misdiagnosis (many of them psychiatric) until the true cause of her difficulties was, if not found, at least narrowed down some.
Wishing you well, Star.
Check out metformin for PCOS. (I know you said you didn't have this ~ but when our daughter's cysts were removed, it turned out that wasn't the only, or even the primary, cause of her difficulties. Yet, the metformin made a remarkable difference for her.
I am so sorry that physician turned your illness into something to attack you with, Star.
So many of our medical people turn arrogant when they aren't able to help us.
You really should register a complaint with the Customer Service section of whatever clinic he or she is affiliated with. Not for your sake so much (too late, now) but so the next woman presenting with the same symptoms will be treated more respectfully.
