Ah I had this.
Suffered for quite some time with a collection of mid sized tags, finally getting them removed 18 months ago.
It was all fine, day surgery home that eve. But on days 3 onwards was painful recovery.
I was extremely focused on eating fruit. And more fruit to keep my bowel movements loose. Plus drinking loads of water. Had some Solpadol as pain relief from pre surgery timed, but it caused contlstipation which is not desirable.
By the end of the week I was quite comfortable though. With one awkward stitch that hadn't dissolved and was irritating me. I popped to the GP and the nurse removed it.
At a check up afterwards it was noticed that there was a small one left behind, so u was booked in for that removing too.
Recovery for that was a doddle. I was pretty much fine the day after.
I believe that the recovery first time was because there were five or six tags removed. Hence a lot of stitching and raw skin. If you only have one, then it may not be too bad at all.
Good luck. Try not to worry about it. It will be worth it.
