I think that is what it is but slightly worried it could be some sort of spot/abcess. I’m aware of it and it not very painful more uncomfortable . It’s on the margin of my bum hole it feels huge but it’s probably a bit bigger than a pea but smaller than a grape. Difficult to see it! Sending myself into a bit of spiral worrying. Don’t want to waste gp time unnecessarily or have to show my bum unless really have to.
