I am post-TT for 1 month, and I can safely say the surgery was a breeze for me. The pain was very, very manageable and I only needed regular strength Tylenol for pain when I got home two days later. The only real discomfort I had was from the position they had my neck in during surgery. I had a lot of muscle tightness and a headache caused by a combination of the Vicodin they gave me in the hospital and the stiff neck. With this in mind, if you have neck problems anyway, then ask for a neck support pillow and some hot packs to relax the muscles. Maybe even a muscle relaxant. My muscle/joint related neck discomfort lasted for a week or so, though. But the actual thyroid surgery wound healed very quickly!
I was hopeful, too, that my FNA was wrong, because I received the same diagnosis as you did. I had absolutely no symptoms - thyroid tests were normal, the doctor couldn't feel my nodules (three of them). My nodules were discovered during a carotid artery ultrasound. I agree that you should thank God yours was also found early. It has truly given you an advantage over those who went for years without knowing. Nothing is an accident, I honestly believe that! Take care. I just found the site, but it looks like there's good people here to help you out if you need it!
