so that or a ingrown hair follicle.
What about a cyst?
Look, an ingrown hair is extraordinarily painful. It will be a large bump, very easily felt with the tip of your finger, that will be in a crevice (armpit, asscrack, inner thigh). It will feel like the size of a grape 80% embedded in you like an iceberg. You'll be able to break it by pulling it up out of your skin. It will explode with a gush of pus and blood and will be the most terrible pain you've ever felt.
Is it like that? No. Then it's just a bump. If it's a zit, it'll heal naturally.
Not going to continue explaining skin infections to you. If you're that concerned about a small white bump on your balls, go talk to your dad.
