A., everything is going to be fine. I had thyroid surgery in January and had the left half of my thyroid removed. After lots of tests prior to surgery, they still couldn't determine that it was NOT cancer so we opted for surgery even though the doctor said (keep this in mind) that the chances of someone my age (30 at the time) having cancer was less than 4%. The surgery went well except that, during recovery, I developed a hematoma (blood clot) behind the incision and they had to take care of that before I could go back into recovery but I think that was because I was a smoker at the time (I quit after the surgery & haven't started back). I stayed at the hospital for about 24 hours and was on pain medication so I was rarely conscious. If your situation is the same as mine, there's not much you can do to be more comfortable except maybe have a pillow or blanket from home. You'll probably sleep most of the time. The worst part of recovery at home was that the mega-antibiotics I was given made me nauseous so I'd take a pain pill with each one so I could sleep through the nausea. Other than that, after a few days I felt fine although I did tire easily. I'm prone to keloid scarring so aside from that, the scar isn't too bad. At first I wore scarves and high-collared shirts but as summer approached, I figured "screw it" and decided not to care about the scar. A little bit of make-up covers it enough. Also, even though my doctor ran tests and said my remaining thyroid functioning normally, I gained 10 lbs within 4 months of my surgery. Since you're having your entire thyroid removed, you may want to think about starting a regular excercise program if you don't have one already. I joined Curves and love it!
I hope all of this is helpful. Keep us posted on how your surgery and recovery goes. Good luck!
