Artist -- I had my TT about 10 days ago and was terrified before surgery. But it was the easiest surgery I've ever had (I've had 4). The pain level was not nearly as bad as I thought it would be and I was up and sitting in a chair four hours after my surgery, talking and laughing with family....plus the main meds were fantastic.
My operation was due to a very enlarged substernal goiter that also had a suspicious nodule, which turned out to be benign. I got the results back in one week. My voice and breathing are still weird, but other than that, I already feel so much better than before the operation....I wouldn't have imagined that one week after surgery I'd have been going out to lunch and a movie, but I did! I'm now on .100 mcg of synthroid and the ENT said it will take about a week for it to start working.
Best of luck on your surgery and please keep us updated!
