How to fix halo effects in photos?

About eighteen months ago, I dealt with a stye on my left lower eyelid—a little pearl-sized bump. It finally cleared up after two months, but now there’s this tiny growth right where it used to be. I suspect it might just be some leftover scar tissue or a lingering cyst, though it isn't painful or inflamed at all.

I was wondering if anyone here has had a similar growth removed and what that experience was actually like? Did it hurt afterward? And how long did the healing process take, I guess?
Thanks
