Its been a long time since I have injected anything but recently did a gluteal injection that caused almost immediate pain. Figured it was just PIP as I'm not used to it and the debt injections hurt like hell also. Almost a week later the pain has yet to get better and it remains very warm to the touch. I feared it was an abscess and drained it. However, the fluid that came out was very red not that white green color excepted with an abscess. Im wondering what this could be as it seems to have developed to early to be an abscess but has had fluid buildup. Put myself on antibiotics as a safety measure.
