After a cyst has been squeezed on penis shaft

Hi, hoping for some advice.

I had a small bump under the skin midway up the penis shaft which after a month or so I couldnt resist squeezing and it popped kind of like a zit with a solid white discharge coming out.

Now I have a small white/pink circle with a darker centre, no pain, itch or anything. The problem is that the healing sems to be taking a long time because it is on part of my shaft where it folds up. Any ideas how to speed the recovery of this?

Also sounds like it was a sebaceous cyst, any ideas?

Any help would be much appreciated.

I apologise if this has ben posted twice but I couldnt find the original post.

Cheers
