Woke up with this lump just below the crease where my belly starts. It's redder/ purple IRL. It's not sore when I leave it alone. I've prodded it and pulled out some hairs and now it's stinging a bit. When I squeezed it clear liquid beaded up where I'd just pulled the hair out. It looks like there's a black dot in there. What is this and what do I do? I'm a bit worried it's turning into a boil...
