O_O Well, okay then! I'm glad it's not severe. ._.
Hmm, my mom presented a related theory: When I was really little, I had scarlet fever (not sure if that's what it was, I had a lot of things when I was little, before I got my tonsils out--may have been whooping cough, which I had several times) and my lungs swelled up, and the doctors said it might hamper my heart and lung development if I kept getting sick, so they took my tonsils out and I pretty much never got sick again, but maybe there was a bit of lasting damage from that?
