Congratulations on completing your surgery!

I had many stitches taken out long after 5-7 days when it was my next follow-up visit after surgery when my ENT said the wound hasn't fully headed yet, as is usually the case with radiated tissue, but see you had none. Although, my recent surgery, with non radiated tissue involvement, I didn't have stitches taken out after 14 days leaving the hospital, 21 days after surgery, as this is what I could schedule. I don't think it's set in stone to have stitches taken out 5-7 days after treatment, and may not be a concern as Christine mentioned, except unusual symptoms. You can always call the clinic.

I had luck with a small electric coffee grinder making the pills into a fine powder that I purchased separate for this.

As far as an Endicronologist, who usually treats hormonal imbalances, I'm not sure either why one was suggested. It could be a deficiency found in the blood like thyroid, which happens often if radiatiobed in the neck, an enlarged thyroid gland, high or low glucose levels or their response to a symptom you mentioned or was found? Could it have been an Oncologist or Radiation Oncologitar instead of an Endicronologist? Funny thing is I didn't know who an Oncologisr was before cancer, and who an ENT was about 2 year of seeing the otolaryngologist, and surgery. My oncologist asked what my ENT said, and told her I haven't seen one lol
Good luck with everything
