Well you need to go to a herp vet and get blood work done to confirm he has gout. He needs his uric acid levels check. And if he has gout they will perscribe meds that he will need for the rest of his life. You can give him some black cherry juice extract along with the meds that should help. That's how my Daizys toes loked at first then her hands and joints become very swollen. So I didn't catch it in time, but hopefully you did.
