I am so very sorry to hear about all your troubles. And, it does sounds to me like you need to get yourself to a specialist - pronto. The Synthroid medication is a replacement for your T4 hormone. I do not understand why they would lower your medication, change your medication around so casually. It's not a medication that you mess around with.
The doctors should not be changing your thyroid medication levels or testing levels more than every 6 weeks. That must be causing you to spin on your head. I would be surprised if you have any energy at all. The medication should not be shifted around like you wrote about. It can make YOU very ill.
I don't have a lot of hope to offer you as I am on my own bitter journey with PCO and hypothyroidism/Hashimoto's. Please go to this web site (

Also, I read that the doc diagnosed PCOS, but it didn't sound for certain to me. Be very careful about accepting this diagnosis. There could be plenty of other things going on with you instead. Consider slowing things down and really getting a handle on what is going on. Your health is worth it.
Good luck to you! and best wishes.
