Teen DS had had no end of problems with this piercing, although the first one was fine. It was pierced just after Christmas and he's had 2 courses of antibiotics already.
This time around he's staying with his dad, and it's suddenly swollen up like this (the front is really swollen and purple too) so they went to minor injuries who sent him to paeds A&E because he's actually quite poorly with it (fever, headache, fainting)
No video of the moment, as I wasn't there, but DS said the doc seemed very excited that she got to pop it! She took some swabs and said 'if anything fun grows on it we'll call you'.
