Hi! My hog was castrated back in November the. We didn’t realize he had a small cyst/abscess it drain on it’s own but then couple weeks ago we saw another one came down he looks like he never was castrated or just one side.... this vet left the stitches they never fell off or he never came and pulled out. So now he has a massive cyst that has been drain but has a open wound. The vet told us to put iodine and dmso gel we have 11 days to show and we need to close this wound and let the inflammation go down. Any tips? Please.
