I can run perfectly fine on a treadmill at a gym for 5 minutes or so at about 7mph. Its not very far/long, but I like it. But if I run outside, the lining of my lungs starts to burn. I can only run for about 2-3 minutes before I have to stop and can't take it anymore. When I do stop the right side of my lung/esophagus is still burning. I'm not keeling over or anything or super out of breath, its just very weird. Then I spend the next 10 minutes coughing up this clear spit/phlegm? that is a little thick.
Why does this only happen when I'm running outside?? I don't get it.
