been using steroids for over 3 years now, but i have a little problem that i wanted to learn why it happened so it does not happen again. it started with a delt injection, i aspirated. when i was aspirating there was white pus that went into the syringe. i then drained like 12CC's worth. then my other injection spots i went and drained like 9CC's worth of white pus from my other delt and glute. haven't had problems since, but why did i get these?
