Poor Kylo! This could be a bad local infection, ringworm, or even mange. Since it is so large and painful when you touch it, I would definitely have a vet look at it. Your vet will be able to determine the cause and get him started on the proper meds to help it heal. Also, you can put a cone collar on him if he is pawing at it or trying to rub it on the ground. You can also give him Benadryl twice a day if it seems itchy. This won’t heal it but it may make him more comfortable. See link below. I hope this helps. https://www.petcoach.co/canigive/dog/benadryl/
