To continue - I had awful allergies of the same type (spring being the absolute worst) growing up and was basically non-functional without Allegra or some other similar drug. I went to Ranger School when I was 22 and we weren't allowed to take any kind of drugs throughout the entire course. So for 3 months I had no access to any kind of my usual meds to ward off the usual misery. For the first 2 weeks it was hell (among other reasons) but then it was like my body just quit being allergic.
Haven't needed anything since, though I'm definitely not suggesting Ranger School as a cure for hay fever.
Now I'm picturing your body's immune system yelling at the wayward cells. "I don't know what your major malfunction is, but I'm gonna unfuck you, one way or another."
That or it was the Motrin, sock changing, and hydration. Cures everything, dontchaknow.
