Small bump on ball sack wall grew larger to the size of my thumb. Never hurt once in the two years I ve had it. Then today I was finally able to pop it. A thick cheesy white substance came out followed up by clear liquid then blood. There is now a small sized hole that is extremely painful, what should I do? It s located in between my inner leg and ball sack where I sweat the most. It originally formed after I nicked myself while shaving. Also there appears to be more inside but I can t seem to get it out almost as if it s fused with the skin.
