I got my ears pierced about a year ago and i recently changed my ear ring then theirs a bump what should i do?

my ear starts to hurt that's when i noticed that the bump was there many people told me to put a warm rag on the ear where the bump is formed at so it can go down but i feel as if thats not going to work because the bump is hard and i would want more opinions from other that have experienced this matter or knows anything cause i rather not go to a doctor im scared of needles and i would'nt want no needle touching my ear

are you wearing fake earrings? Some people are allergic to anything that isn't real silver or real gold. Those bumps are a sign of infection so try different earrings and make sure you clean your ears really well
