<human>: I got the bottom of my belly button pierced in June. It was healed but just recently I noticed a hard bump under my skin right next to it. Yellow puss and some blood come out, is this an abscess and is there something I should do while I wait for my next doctors appointment?
<bot>: Hi, welcome to Chat Doctor forum. Your description points towards an abscess. It needs incision and Chat Doctor. Then only, antibiotics can act. If you have a delay for your appointment, you apply osmotic agents like magnesium sulfate paste, and start antibiotics and analgesics(I usually gives amoxicillin+oxacillin to my patients), gently express out any pus, and keep the area clean. Hope you will find this information useful. Thank you.
