Hot ears?

I've had a couple of threads on here trying looking on advice for my dog's seizures and he has recently been diagnosed with epilepsy.  I'm having  a hard time accepting that there is no cause for his seizures and worry that there's another reason (brain tumor, meningitis?) however, the cost to rule this out is over $4k.

He has no other symptoms than his seizures except he occasionally has hot ears.  I may be overly paranoid looking for other symptoms due to my unwillingness to accept his diagnosis, or is he having a consistent on/off fever?

With meningitis I beleive there would be a fever along with that.  A brain tumor the dogs balance, walking, eyes or hearing may be effected. I don't know what you can do but maybe try some home remdies. Look online for healthier diet. Healthly diets seem to help out a lot problems.My suggustion come from doing alot research on meningitis and brain tumor in general.
