I get this every so often, and it stays for WEEKS if not months, it's sore and weeps often (that's why it looks crusty) doesn't come to a head, and eventually goes away on its own. I look gross because it's so huge
I used a hydrocoiod bandaid on a pimple, and drianed a lot out, pretty sure the purple is just scar tissue / bruising. but now I'm having a bad blister reaction to the adhesive!
