Hi!
Sorry to hear about your lupus scare, but glad to hear it isn't that.
I was just over at the thyroid pages reading up all I could on hypothyroid issues and then came back over here to see what other people were experiencing with PCO and Hypothyroid. The symptoms you reported in your posts seem similar to symptoms that I saw over at the thyroid pages.

I recently found out how tricky the thyroid issue truly is. The pain you are experiencing in your hands and feet is something people posted about as a sign of thyroid imbalance.
I hope this helps!
