With the high BA and crystals, there's half your problems. Let me guess it was prop? Just guessing here since you didn't state. Besides it sounds like your case is going to take 7-10 days rather than 3-5 to clear up depending on the amount. I know your probably freaking out, but if the site doesn't have fever or isn't red I would give it time. No since in taking shit when you don't know what you have. Besides your probably half way there. If it makes you feel better my ass is on fire from my last prop injection, and I can barely sit at my office. But I know it's not and infection because I sterilize all my stuff very detailed and have had the pain before.
Besides you should be half way through the pain by now. Well??
