I had one of those for the thousandth time five weeks back.I ignored it and hoped it would go away,it didn't.It grew and got infected.When it was the size of a shooter marble I went to the doctor,her answer hot packs and antibiotics.Next day it was still there,new answer squieze it until it popped until all the puss and blood clot had come out or surgery to carve it out.I don't like being put under so I said "go for it!"That was like loosing my right testicle all over again and 15 days more antibiotics.Now I have two holes and a big black bruise next to my left nut on the inner thigh.It's a bacterial infection,if you can't get at it go to your doctor.Although it's realy odd having a strange female up in your crotch squeezing a pusstulating sore!
