Lump on scrotum

I recently discovered a bump on my scrotum while I was in the shower. It started off as a small bump under the skin that felt hard but you couldn't really see it. I tried popping it and did extract a little puss. Since then (about 2 days) it has turned redish. It also flares up (3/4 size of a dime) when I squeeze it but it doesn't seem to contain fluid anymore. It looks "sort of" like a blister which is why herpes is worrying me.. but I have also considered it being a cyst or folliculitis? I have had a similiar lump in almost the same place on the scrotum maybe 5 months ago that went away within a week. Can cysts come and go like that? Also I went back to using the same body wash I previously used when I experienced folliculitis months ago. I am hoping this isn't an std or anything I should be worried about..Thanks doctor

It does not sound like herpes or an STD.  it does sound like folliculitis, aggravated perhaps by your squeezing it.  I don't think you have anything to worry about, so I would recommend that you leave it alone.  If it returns again, you should photograph it in case i fades before you see a doctor, but you should then go see one, so you'll know for sure.

Take care.

Also, there was a slight and short- on and off "tingeling" of the scrotum I experienced the same day I got this, I'm not sure if this is relevent at all.

Quick update doctor if you dont mind -
It's been about 3 days since aquiring this bump and it now looks like it is healing, though it is still is quite visible... however 2 new small, small, red spots have developed that do look more like and ingrown hair of some sort..(theyre not raised)
My question is if the 3 day delay between getting these different looking bumps/spots is a case for or against herpes or folliculitus (folliculitis).
Thanks a lot

These also have been itching the past couple days very regularly.
