When I was first diagnosed with Graves Disease, I started on Synthroid. It made my arms very sore from the wrist to the elbow. I changed to Levoxyl, and took it for many years until it was no longer available. I then took levoxithyrene for a while, but it didn t work. In the meantime, my doctor died, and my new doctor put me on Synthroid .75 mcg. I am having the soreness to the point that it is almost unbearable. What are my options now? (I haven t called my new doctor yet. I plan to do so tomorrow.
