Ok heres teh situation. At around 5 pm i shot some b12 into my delt with a 25g 1 inch pin. This was my first shot ever. I did everything, including aspiration. But I keep feeling like maybe its still sitting in the muscle and hasnt dispersed yet? How long after an injection do you know something is wrong like an abscess or something?ITs about 11:30 pm right now and it looks fine except when i flex it, it kinda looks like a lump??
