wierd bumps, maybe blisters?

Hey everybody, I’ve got these 3 bumps on the corona of my glans and was wondering if anybody had a clue what they were. I don’t have a camera yet but as soon as I get one I’ll post a picture of them.

They are located on the topside of my glans right on the corona. I don’t think that they are PPP because they are much larger, almost the size of bb’s for a pellet gun. They have no color and are kind of tender. I was thinking that they may be very small blisters from hanging and using an ADS.

Another thing I observed about them is that they swell up when I hang. Before hanging they are hardly noticeable, very tiny and a little red around them. After hanging they are the size of bb’s and their color matches that of the rest of my glans, which is red. There are only three of them right next to each other on the top of my glans.

Anybody know what it may be?

Maybe I should have put this in the injuries forum……..If a mod would be so kind as to do that I would appreciate it. Thanks.
