Hello, I think you are jumping ahead.
You need to have the tonsillectomy and get the pathology results of that.
If I read your post correctly a CT did not show a tumour. So, take a deep breath and try and relax.
I agree with Paul. I would not wait to have the tonsillectomy. Push to have this done now. Then you can either relax, or go into fight mode.
This could be a number of things and you must get a biopsy of the tissue, or the tonsillectomy in your case, to know what you may be dealing with.
Thinking of you. Keep us posted,
Tammy
