I had a thyroidectomy on 4/16/08 and started on the generic synthroid right after that. The reason for the surgery was nodules and pre-cancer cells( I have had breast cancer and mastectomy 12/06. Since starting it, I have had swelling all over my body and was wondering if it could cause it. Since reading all these blogs, I see it is probably the cause. I am taking 75 mg and was wondering if maybe it's to high a dose.(?) I don't go to my Endo for a month but was planning on calling him tomorrow to see if I can half the dose until I see him-Is that a good idea or should I increase it? I'd appreciate all replies.
