Hyperthyroid, Graves’s disease here. Don’t let the name scare you; that is the worst part!!!
My history, I thought I was going insane, I could not sit for any length of time, could not concentrate to read, night sweats, racing HR, trembling hands, quad pain and constantly thirsty all symptoms of Graves disease. I was lucky, I did not go into Thyroid Storm; my cousin’s son did. That condition can be extremely serious.
I opted for having my thyroid nuked. The nuking process is like something out of a science fiction movie. A horse size single pill (the pill alone costing something like $5,000!) with only a couple day shelf life sealed in lead canister with the radioactive logos on it that you open yourself, in a lead shielded room with no one else around. It was a bizarre experience. Then it took almost 2 years to really get my meds stabilized; it is a moving target, based on blood work results and your physical feelings.
While you figure out a course of treatment, there are meds that can be prescribed to control it temporarily.
My life is very normal, as are most people properly treated.
All in all, if yur gonna have a disease, this one is not a bad one to get.
