I had a navel piercing done 2 years ago... it looked okay after, but maybe 5 months later I decided to take it out and when it closed up I forced it back in, which made it inflamed and I supposed infected... and months later I switched rings and a large bubble like bump appeared around it... I really only cleaned the piercing site during the first few months I had it and then just cleaned it in the shower thereafter. Overtime the bubble shrank a lot, but to this day it is still there. What should I do? Is the bump a big concern?
