| | Ear bump
This is more of a curiosity thing then a worry, but I get large swollen bumps on the back of my ears. It's only 1 bump per ear, but they stay for months. After a while they get a little brown spot on them I can tear off and drain them through, it's mostly, blood; but there is also pus and what is seemingly blood, but had the texture and stickiness of maple syrup. They always appear on the back, on the lower part in the little concave area. I'm just curious what these are and if they are any cause for worry. I do have acne, and I've thought that it may be a nodular cyst, but this bump is very tender and doesn't really hurt, and it is purple, unlike my pink nodular cysts. Any ideas, anyone?
