ive had pain for over 10 days before. if there is no redness or heat at the surface it is not AN INFECTION period. ive had this scare so many times bro and you are fine. the first time i went to a doctor and was given an anti inflammatory to get it down, but the second time i toughed it out and used a real hot compress and massaged the shit out of it. the swelling is so big its like a banana is resting on my ass cheek. i know its scary but you don't have an infection unless you have heat or swelling at the surface
