In elementary school I had chronic bronchitis. I used to be a state ranking swimmer 2 years ago, so I figured I conquered that breathing problem. However, every time I run (with this program or not) I can't seem to go long without my trachea feeling like it is on fire. After I run I will feel like I have something in my throat for up to 4 hours after as well as small coughs. My doctor has little to no input on this. What is this? Does anyone else get this?How can I combat this? It's getting discouraging...
