Sounds like a hematoma that ended with cellulitis not an abcess from bad gear. Rare, but happens in the quad because of the vasculature. Know a doc that treated a lifter that had that same problem, but it was from a hematoma resulting from hitting a small arteriole while injecting. Tried draining it themselves, described the same type of fluid, then a serious infection set in because of all the dead tissue and required surgery. Posted a pic of the mess a long time ago. Took a 2 months to close and required IV antibiotics. Just be careful with quad injections.
