My allergies have been horrible today- so bad that none of my emergency allergy medications and measures are working. While capturing the satellite pass, my eyes watered so much that I couldn't read the frequencies clearly; once back inside the symptoms didn't let up. When this happens I find myself desperately searching for the cause, but the thing about allergies is that sometimes there isn't one that is clearly defined. I am speculating about dust, springtime pollen, a low immune system, or lack of sleep- but none of these feel like the obvious source.
