My DD who is 14 got her cartilage pierced when she was in tenerife about a month ago with me, the place was very clean, the piercer wore disposable gloves and washed her hands and everything was sterile and it has been fine until last week when she was at her grandparent's home it got very red, painful and swollen and infectef so she bathed it in warm water and sea salt 2/3 times a day and now she is back it keeps bleeding and getting like a bit of crusty blood around it. Should I ring the GP?
