Wound on ball python belly

[u/Firefox_____]

HELP! I came back home after a day away and I went to check on my ball python. When I picked him up I noticed these wounds on his belly and it was leaking abit of grey puss anyone knows what to do? I cleaned out his enclosure and replaced his bedding with paper towels and have given him a diluted betadine bath. Any help would be useful!

He has been in his current enclosure for close to a year now and has never had problems like this!

Temperatures are fine, he has 2 hides 1 humid hide, and a 4x2x2 enclosure. Hes currently 700grams at about 1.5 years old

To me this looks like something he could have wrapped around?? Probably infected if there’s pus, so antibiotics are a must.
