I agree with those who say lay low if the cold is in your chest.
I came down with my first cold in years the week before Christmas. It started as a head cold, but traveled south, and turned into bronchitis. I finally went to the doctor who put me on a round of antibiotics. That helped, but the bronchitis seems to have triggered my semi-dormant asthma. I've been using an old inhaler with albuterol so old it's probably not helping much, if at all. I'm hoping to get an appointment tomorrow to get this development checked out and get a new inhaler prescription.
I had been hoping to at least try a short easy ride today, but the temp is low enough outside for me to hesitate filling my lungs with cold air. It's been about a month since I've ridden outdoors and it's making me crazy. I feel like I've lost my endurance base completely. I'm hoping it's just the asthma related chest tightness that's making me feel this way. I haven't even felt like trying the trainer, but may give it a try this afternoon if I feel up to it.
Hope you feel better soon.
