Hi. The bleeding after 10 days of tonsillectomy
is usually due to infection ad separation of the slough ( the natural covering over the raw surface in all cases). High blood pressure
can increase bleeding. I hope they have advised you of diluted hydrogen peroxide
gargle ( many ENT Doctors advice , although not all ). Nothing to worry about the stitch spiking out. This is normal. Go for cold liquid diet
. Nothing will go wrong after 19 days of surgery.
