My DSD had grommets, and when she has an ear infection the discharge is bloody, gooey and jsut plain disgusting.... she was taken to the emergency and a GP at the time and we were told that it was doing what it was supposed to be doing... however it also means that she did have an infection and I can't recall if she had antibiotics as well. I suspect it would make sense that she did (or should have!!)

I recall it was simply gross (can't recall if it smelled - but then I didn't get that close! - it was DH's job to clean up and check out that mess.... after all she's HIS daughter...!!

lol having said all that, go to the dr and get it looked at - probably its all okay but its not plesant and maybe they can give you something to clear up the underlying infection :-)
