what are signs of a infected ear piercing for ex. is your ear supposed to hurt a lot and be red or abnormal amount of time?
Piercings (although I have plenty) are unnatural and not meant to be inside of the human body. It's perfectly normal for the piercing to hurt, swell, get red, itchy or irritated. As long as you keep it clean and avoid touching it during the healing process, the piercing should be fine. If it starts to ooze yellow fluids and pus, then you should be concerned.
From my experience, when a piercing is infected the skin around it will turn hard, and red. it'll probelly be uncomfortable and itchy. hope I helped!
Or if it forms any bumps, lumps, etc.
