It’s hard to tell from the pictures Has he got any wire/mesh platforms, wheels, or ladders in his cage? Walking on wire can cause painful blisters called bumblefoot. Also check all his toys for sharp edges or splinters. What substrate does he use? Some woodshavings can be sharp If his substrate spikes your hand when you squeeze a handful, then change it to something softer.

Apply saline solution to his paw twice a day until it’s healed and remove any sharp or rough objects. You can make saline solution by mixing 1/2 teaspoon of salt in a cup of boiled water and letting it cool before applying. Salt is a natural antiseptic and will help his would to heal as well as clean it. Do not apply any human medications, and if it’s not healing within a week, looks worse, or infected then take him to a vet asap!
