Hypochondriac, I think you spell it.
I don't know much about cat medicine- could it be ear mites? I think I read somewhere that they look like raised brown lumps on the inside of a cat's ear.
That could be wrong though- I think it might be best to check with your vet. Perhaps you could ring up and check, so you don't need to bother the vet with making an appointment? Then s/he can advise you.
