So I get cystic acne regularly. This particular pimple started out tender and became squishy. Typically after a hot shower I can pop the squishy ones. When I pop them a thick stream of pus jets out, then it swells, overnight it scabs and heals after a few days. Not this time. Of course the jet stream of pus came rushing out. It swelled. I went to bed hoping it would scab while I slept. I woke up to find a bubble slightly smaller with two tiny holes leaking clearish red fluid, on its own. It s been doing this now for weeks non stop. The fluid is never ending. I m worried its infection and when it finally does heal, if ever, I will be left with a huge gaping scar. What is this?
