Evan's Asthma and Allergies

So Evan has asthma and allergies, including exzema, and has had them since he was around 18 months. His asthma is triggered by his allergies, which are everything that they test for. All 42 of them at the highest level or the second to highest level. No surprise, I just feel bad for him. His asthma is also triggered by exercise, mostly when he is already feeling bad, and the cold, and when he is sick and everything else under the sun. That's what it feels like anyway.
They were bad in Texas off and on and seemed to peak at its worse the summer of 2006. He had to be hospitalized overnight in July that summer. The picture is of him playing in the playroom on the peds floor at Wilford Hall in San Antonio. James was gone to Qatar. Thank goodness we still lived in Texas and I didn't have Ava yet. Ryker had come to stay the night with Evan and so I called Mom and Dad and they came. Mom came with me to the hospital and Dad stayed at the house with Ryker. That was an experiance.
Then when we got here to Alaska, the first week we were here, Evan's exzema cleared up. The only places it was bad was behind his knees where he sweats the most and it flares a little when he gets overheated from blankets and such. So we thought maybe things would be better. We were wrong. Last summer was the first time we had to call the ambulance to take him to the ER. The attack just creeped up and we couldn't get it under control fast enough to get him there ourselves. This was not the first ER visit by any means and every time we have been, he gets breathing treatments and a round of steroids (prednisone) to take for 5 days to help his lungs not be inflamed. Those are not fun days, let me tell you!!! We have worked with his pediatrician and results have been ok. We now see a pulmonologist and he is good too. But things just aren't getting better.
He misses so much school and if I thought that he would be better off taught by me than in public school, I would totally and immediately home school him. But I feel like he would fight me every step of the way and that he needs that socialization he gets from school. He loves it there and all the kids and his friends. He is not behind and he has a wonderful teacher who I keep in touch with and we make up all his work.
Tuesday we were in the ER twice and he is taking his steroids now. Usually he can be back to school within a day or two, but this time it is really bad. It just really worries me and I hate for him to not be able to be a normal little boy. Prayers and research about homeschooling are definately in abundance these days.
