Today I had to leave school early for a doctor's appointment. This appointment was a follow up for a previous appointment that took place last November. The story behind this is that I was having trouble breathing during a lot of track and xc meets, so eventually we get around to mentioning this the doctor when i got my annual physical in the summer of last year where I was told I had exercise-induced asthma and then referred to a specialist. Then in November, the specialist said that he thought that the issue was with my vocal chords doing the opposite of what they were supposed to do (they were apparently contracting and restricting my oxygen intake when I inhale and releasing any air reservoir when I exhale). Today he ran a test that he couldn't run before due to lack of equipment the would measure the amount of a certain chemical in my bronchial tubes that everyone produces. A normal person produces about 10 parts per billion or less of this chemical, from 10 parts to around 14 parts per billion the odds of having/getting asthma get to be around 40% and as it gets closer to 20 parts per billion it gets closer to 90% chance of getting/having asthma. My body produces 40 parts per billion apparently. Other than that the appointment and the rest of my day went perfectly fine, and I'm supposed to in for another follow up in November.
