Hi, welcome to HCM.
problem -- 2 episodes per year is not an indication for tonsillectomy
. However you say you are having sleep apnoea. This definitely is an indication for tonsillectomy, as lack of sleep can pose a lot of problems -- personally and socially.
But again you are suffering from high blood pressure
you say, which probably is not coming down with the concor 5mg you are taking.
High blood pressure is a definite risk for a tonsillectomy. Tonsils being vascular structure, tends to bleed even in normal persons. In your case there could be life threatening bleeds also.
Therefore i suggest you first go to your physician and ask him to change your medication or increase the dose of your present one, so that your BP normalizes. Thos may even take a few weeks or months. But this of paramount importance-- even more than your surgery.And again surgery is a must fort you!.
Hope you get well soon.Good luck.
