Hi Curtis,
An infection has probably set in. Wound may need to be drained and your kit will need antibiotics. He must see the Vet Today!!
This is serious and he is probably in a great deal of pain.
Good effort to help him, but beyond your expertise now.
Please let us know what the vet has to say, we all learn from each others experience.
Good Luck and hope the little guy feels better real soon.
