My cat is 5 and he had had this issue since he was a kitten. Twice a year I have to take him the the vet where he gets a steroid shot and an antibiotic due to the inflammation. It gets to a point where it bothers him so much he starts to scratch at it and it bleeds. The Vet says it's "allergies". After the shots it slowly goes away and then 5-6 months later it happens again. I feel there are better answers and I sick of giving him these shots into his body. Any ideas on what it could be?
