Sounds like you guys are doing your homework
One note on the steroid. While I am not a steroid fan, with EGC the steroid injection can in some cases permanently resolve the situation. I am treating a cat with that right now. My protocol, besides allergy treatement and food change, is depo-medrol injections. We are going to use one to three injections only. If that doesn't work, then we will use other options. Depo-medrol is not my favorite drug, and does present risks for diabetes, kidney disease, etc... however when employing them on a single or limited basis, the benefits may outweight the risks.
The following an excerpt from Wendy Brooks D.V.M., D.A.B.V.P. from a EGC client handout, "In most cases the eosinophilic granuloma responds to cortisone derivatives though often an aggressive regimen must be used. Typically an injection of long acting corticosteroid (such as Depomedrol) is given every 2 weeks until the lesion is gone or for three injections whichever comes first.
Most eosinophilic granulomas resolve with one injection but some are refractory and will not resolve until antibiotics are used. Some are more refractory still and require more exotic treatments."
If holistic measures are successful, please let me know. Anything that may be useful for a patient as well as reduce steroid use is always a good thing.
Good luck
