you need to be specific, before u ask..."what is an abcess?"...who told you that you have one, what does it look like, how long ago did u inject, what injection procedures did u use, exactly how does it feel, is it getting worse, is there a red spot, is it growing, is it warm to the touch. dont ask how to fix something u dont even know if u have. cuz we will send u to the doctor if thats what it is. more info please
