I had at TT on May 19th for thyroid cancer...it was one of the easiest procedures I have been through. 3 weeks later, I feel back to about 100%. There are few risks to the procedure and tons of us on here have had it done, so rest assured, you are in great company. You will be absolutely fine and I am guessing will feel so much better after the surgery!
Good luck!
It's good you're getting yourself informed.
I had mine out because it was growing all over the place. The problem was discovered while preparing for another operation. Seems it was quietly making trouble for me. Yours seems not so quiet and seems more obvious it's making trouble. Ergo, I can see how a dr would recommend getting it out. I know it can be unnerving to hear that, but I'm now glad I went along with it. Hope you eventually feel the same.
We are here for you. Good luck.
