Haven't been riding for the last two weeks. It's killing me since the weather has been so nice. I went to the doc and he promptly sent me to the ER. After and EKG, blood work, chest X-ray, and exam of my lungs and heart, they've returned a preliminary diagnosis of exercise induced asthma and sent me home with an inhaler (they said that I'm as healthy as a horse and are perplexed by my recent shortness of breath). Freaking great! I have to schedule a CT scan, then it's another appointment with a pulmonary specialist next Wednesday. I hope it's allergy or infection-related (although I feel fine otherwise) because I've been really happy with my cardio performance for the last few years (with the exception of the shortness of breath the last month or so that prompted my visit to the doc). Anyway, I decided that it's best not to ride right now until this gets sorted out. I hope everyone else is enjoying their commute.
