Other than that two or three other
bumps have appeared in this time, but none have swelled up, burst, and crusted over
on their own. By chance I have been the one to pop these, but not on purpose (for example: I had been in the pool with boxer-briefs, and getting out they clenched up to my skin, I was pulling it away when i accidentally squeezed one of the bumps). While exposed the bumps hurt minimally, unless something touched them with a good amount of force.
