My son had a laparoscopic surgery when he was an infant. Every now and then, 10 years later, the tiny scar fills up and gets a black head. Got this cute little thing out of it just now! (No children were harmed during the squeezing)
Ingrown hairs, boils, or cysts? Appeared after shaving, caused by chafing from wearing pads. Feel like pea sized hard lumps beneath skin. More info in comments
Ear Hole Update! it's been a few months, and all they've confirmed is that it IS a cholesteatoma...and a big one at that. Waiting for a pre-surgery consultation, but today a piece literally broke off in my ear causing quite a bit of bleeding and pain ð
