I had mine removed about this time last year and was off work for 2 weeks. I notified the CAA Medical section who just said I could return to flying when I felt ready, no need to let them know.
They are cut out under general anaesthetic and the wounds are left open, i.e. no stitches or anything. My throat was very sore but I got an infection in the wounds which required a course of antibiotics to clear up. The pain was pretty bad but it was worth it in the end. You are encouraged to eat as normally as possible, and they do recommend TOAST
as it helps keep the throat clean. I struggled due to the infection and was eating very little for a few days. You are given strong painkillers which help a lot.
Just trying to give an honest account of my experience. Try not to let it put you off as you will be glad that you had it done in the end.
