Should I change to a flat back stud?

So I have this irritation bump and i’ve had it for around a month and something days, it’s been going down but I’ve been thinking of going to a piercing shop to get it changed. I’m not sure if I can because I’ve had this piercing for around 2 months, I’ve tried to look up and it says I shouldn’t but when I look on here everyone says to change it to a flat back cause I currently have a corkscrew due to me being pierced with it. So maybe a professional piercer on here could give some advice?
