Did you consider that it's return may have been connected with your Covid vaccines? Do you remember date you had the shots? I got my first Covid vaccines in 3/2021. After reading these posts on triggers for GD, I am reluctant to have ANY vaccine or injection. I was supposed to have a scan that required iodine contrast , with a common side effect of rash and itching, so I cancelled it. I am now in limbo wondering what to do.
