I got my industrial pierced about 5-6 months ago. Today right when I got out of the shower I went to clean my piercings as usual.. which I clean at least three times a day with wound wash saline, and once with satin soap. I went to clean my industrial, and notice on the inside of the top part of it was quite a large bubble. Looks as if there could be pus inside considering it's white-ish. Just wondering what should I do about this?
