WELLL im 13 years old and i pierced my lip last week and i didnt serialize the needle but i put alcohol on it idk if that does anyhting but i tried cause i didnt have any poroxyd.when i got home from school my mom told me to take it out then i did then 4 minutes after that i put it back in but where you poke it through the lip well that part it closed up and it was the only part closed up. so then when i was looking at my lip one day i saw that the part where the needle went through the first time turned yellow and it is like a circle. is that a common side effect or is it that it is infected? thank you so much
