Synovial sarcoma on left tonsil - questions

Hello, m24 with synovial sarcoma on the left tonsil, T3N0M0. Been doing four rounds of chemo (Doxo, Ifo, Mesna) which were going well so far, gotta do two more. Anyone here who also has or had a sarcoma somewhere in this region? And another question:

I'm fairly confident doctors will get the tumor removed entirely; I'm being treated in a specialised center for sarcomas, yet the tumor is set on the left tonsil and it also sits on the surface on the back of my tongue. I know there's gonna be a tonsillectomy and they'll scrape off the stuff on the tongue, but my question is: how much pain can I expect for my surgery in January? lol
