Craftybear-
If he has the same kind of nasty infection I did, it's a real boogerbear! They had to change the IV antibiotics three times to find a pair that would zap it. Once they found the ones that worked it was only a few days till the swelling and redness was nearly gone and they let me go home with just a couple of bottles of pills to take.
Glad to hear they think they've found the magic combo!
