You could also try using a vibrating massager on his inner thighs- it helps the ears drain (sort of an acupressure sort of thing). And you could try putting garlic oil in his ear, then have him lay with that ear down on you (skin) or on a heating pad.
Hope he is feeling better soon!
BTW- I found this thread because my dd started having yellow gooey stuff frome the eyes today, so I'm glad this thread was here to read.
