Okay, I put a pin into the injection site and aispirated to see if any puss or anything of the sort came out.. Well I got Blood. Not sure, but I might have put it into a Vein this time. Anyway most likely I hit a vein and went thru when I injected, so maybe it is irratated because of that. It is not very painful or lumpy unles I flex the Quad FULLY then if hurts and there is a noticible amount of swelling. I started taking amoxicillian (Antibiotics) today Just incase an infection started.. If not gone in 5 days - off to the doc I go..
