My spur thigh tortoise was totally fine, then for the first time all summer (weather finally cool enough here in az)I took him outside to get some exercise, fresh air within 5 min I notice him trying to rub his eyes and then all of a sudden they were all swollen like from an allergic reaction. Help? any suggestions? I flushed his eyes with water incase of sand in his eye etc but still swollen and I'm freaking out! Thanks!
