Hiya clarty,
Glad you're doing ok. What you might have is skin tags. They are not usually hardish, but soft like loose skin as the name indicates. When you think of the procedure -- erm -- you know what I mean, things are turned a little inside out for the surgery. They don't sound like piles. Sound like a bit of excess skin.
I can understand your annoyance after what you've been through, but it is only recently that you had the operation. If you can put up with it for a little while longer and they don't go back where they belong, go back to your doctor. The thing is if they are still bothering you a bit later on, they can be surgically removed. If you can go through that again that's ok, but if you think you can put up with them once the soreness of the operation has diminished then that might be the better option for you.
I hope things improve for you soon.
