Emmett's poor ears!

After finishing his antibiotics we found that Emmett woke up with a fever two nights later. We thought he was just getting some new teeth and just dealt with it. Later in the day we found out he was getting hives on his face after having a second fever spike. The fever never got over 100 but the hives scared us enough to call the doctor and asked to be squeezed into a very busy pediatric schedule. Of course by the time we got there (about 15min) the hives were clearing up and Emmett's fever was gone. After checking him over the doctor said that he had another ear infection and that she was fairly sure that it was not the same one but one that had come after the first double infection cleared (thankfully just the left ear this time). She said that it looked like he had a virus and that she had been seeing a few patients who were getting hives as a reaction to viruses. She said we would do another round of antibotics (that will be 20 days of the stuff this month!). She also said that we could give a very small amount of benedryl as a last resort. Does this sound odd to anyone else? It did to me. Since she went to med school I thought I would trust her but also keep my own ideas for a while and let her know if it got worse since this was not life threatening just uncomfortable for Emmett. Anyway after about 4 stores no one had children's benedryl....all sold out! GRR! So we decided to deal without it for a day and search again tomorrow. Hoping that the antibiotics would work quickly. The next day Emmett continued to have fever spikes only two. Each brought on new hives that were worse and worse. I called the Dr. She said that she still felt it was the virus and how his body was dealing with it. So after benedryl I decided to give it one more day and (3 doses of anitibotic) before I called another dr. Well guess she went to med school for a reason because the next day no fevers and no hives.... The dr. called me to check on little Emmett and said that she hadn't heard of them coming and going with just the fever but that they usually stay so we will see the next time he gets sick (or hopefully not and he will stay healthy) if that is his body's way of dealing with fevers-hives. Well Emmett does like to do things the hard way...
