I had half my thyroid out in Oct, frozen section in OR looked okay so they left the other half. Of course, the final pathology report showed cancer--so in December I had the other half out.
I had no effects at all from the first surgery--left about 2 hours after. I sucked on some hard candy, and took maybe 2 tylenol for pain. I found it VERY helpful to wear a baseball cap when I laid down. This allowed me to pull my head up by pulling the brim of the cap--it was a trick one of the nurses told me. It was a very valuable tip.
Second surgery went just as well--since I had the full thyroid out this time I did need to spend the night. My parathyroids were fine, and I was discharged at 8 the next morning. Once again no ill effects.
My scar is very minimal. My surgeon in addition to being a endocrinology surgeon is a board certified plastic surgeon, no staples just strips and glue. Both surgeries were done using the same incision and it is probably about 2 inches.
Feel free to PM me if you have any questions. Since I had 2 surgeries I have a bit of a unique perspective. If you are in the Chicago area I would definitely recommend my surgeon.
