I'm allergic to corn

I have been riding with Victor on the combine harvesting corn up until last week. When I rode with him while he combined wheat, I had no problem with allergies or sinuses. This corn, however, gave me a sinus infection. This problem started Saturday before last when my ears starting ringing. As four days passed, my ears were still ringing and I felt horrible! I had intentions of going to the doctor last Tuesday afternoon, but I canceled to get caught up on some homework. Last Thursday morning, I woke up at 3:30 A.M. with a fever of 102, so off to the doctor I went. He said I had fluid in my ears and I was clogged up in the head (more than usual!!!)and gave me Amoxil and told me to stay home until I was fever-free for 24 hours. He then asked me if I was usually bothered when the farmers were out in the fields combining corn. I told him that it never bothered me before, but I did not tell him I was actually on one of those combines. He proceeded to tell me that a person can develop allergies at any given time. The corn harvesting is almost complete, but next are soybeans. I will ride on the combine one night during the bean harvesting and see how I react. I am hoping that it is only corn I am allergic to!
