Hello, I had the right side of my thyroid removed 4wks ago due to a large lump appearing there over the space of a year. I havent seen my dr yet as my appt isnt until next week but I was just wondering what are the chances of it re occuring on the left side? I have found out that it is benign but still dont know what it was? Also I am very concerned about weight gain as this is what everyone on line seems to complain about re after effects?? So far I seem ok but would I know by now if I was going to gain weight or could it take longer before I would know? Thanks, Emma.
