This happened to one of my pigs, a cyst formed on her right hip, burst and then became infected. We tried keeping it open and ‘empty’ and clean as the vet was worried about surgery on a four year old pig. But she hated it so much and it was so stressful for all involved that I opted to have it surgically removed. Poor potato’s second surgery in four months! The same vet did the surgery as the last time and they were confident doing surgery on a dinky pig. She was totally fine and the cyst capsule turned out to be much larger than they thought - it would have been impossible to keep it clean. She was back to normal in a couple of days and the wound healed really fast once again.
Anaesthetic isn’t as high a risk as it used to be for piggies, though of course any anaesthetic carries risk for any animal, an experienced vet & team make all the difference (and loads of metacam for the recovery!)
Hope the antibiotics do the trick for your little flooff, but it’s not necessarily game over if they don’t.
