Glad to hear you're past the worst parts anyway!
My surgeon said the issue in the back of my throat now is that the healing areas are scarring--which is normal and they're kind of tight. Over time the tissue will relax and become more supple. Hopefully this is similar to what you're feeling. I told him my professional singing career was in jeopardy! He said it could be a few months and often tells his professional singers up to a year! UGH! I guess I'll have to cancel my plans for door to door caroling! Ha!
This too shall pass--as they say!
I'd have to say my experience was much more positive---and i would recommend this procedure, but I completely understand your point! Maybe a different surgeon or researching how the procedure is done there (I see you're in UK)-the technique used with me was "intracapsular" performed with a "Coblator"-and definitely need to have post-op pain medications which DO NOT include NSAIDS!
More than anything I am very hopeful for a full recovery and the end to the crazy horrible episodes of tonsillitis. I have been miserable. This was worth it for me--if it means I get to avoid all of the illness!
Continued best wishes for a full recovery!
