Ii Went On A Bike Ride Last Wednesday And It

Ii went on a bike ride last Wednesday and it was a cold crisp day. When coasting downhill pretty fast, my lungs filed with cold air and sting a little. After the ride, I felt the stinging for several hours after and had a sense that I wanted to cough and clear my lungs. Since then, I still get the stinging sensation in my right, upper chest and back of my shoulder blade when I breath deeply (yawn) or cough. I can compare the stinging to times when I've accidentally breathed in my own saliva while laughing and talking at the same time....does that make sense? Should I be concerned?
