Gave steroid shot which stopped symptoms for a month. they came back and vet said to give zyrtec. 1/2 in am other in pm. Helped for a couple wks. Now symptoms are back. Can anything permanent be done to stop this problem ?

If Bugs responded to steroids and antihistamines it may be an allergic reaction. You may talk to your vet about allergies caused by flea bites, food allergies, or environmental allergies. In some pets, 1 flea bite can cause a body-wide allergic reaction. He may also need a hypoallergenic cat food for a few months. Common causes of increased eosinophils are allergies, parasites (external and intestinal parasites), and fungal infection.
