Hello Randy:
Not sure what you mean by "The taste buds at the back of my tongue suddenly enlarged about 10 days ago." Do you mean your tongue/throat swelled or something like that? I know my taste buds went berserk during and after treatments, and still are messed up, but what mine is the crazy tastes/mucus I have all the time, still. If the oncology nurse didn't react to what you told her, it probably is caused from the tonsillectomy, but I would tell my oncologist and get his/her opinion. Having a clear PET in June is a plus, so hopefully the taste issue will diminish soon. Good luck.
