I think you are going through thyroid madness! I would recommend talking to your doctor and see if he will try a different medication. There are a variety of thyroid medications available that sometimes can really help. Synthroid is a T4 hormone only. There are also T3 hormones that often help as well as natural hormone medications. Your doctor may be a little hesitant to try these but I convinced my doctor and it helped me a so much. I’m on a combination of T4 and T3 (levothyroxine and cytomel), made me feel like a new person after I started this. Good luck.
