This is normal for 3-6 weeks (sometimes more) after surgery but talk to the surgeon to make sure there is nothing wrong.
Had/sometimes still have the same. Surgery 6/24. It is greatly improved but I also had to go hypo for cancer treatment ri131 and it got worse during that time. SO... I am counting on it improving again now that the treatment is over and I am back on medication for hypothyroidism. Good luck!
