I used to run a lot, but now I would say that I am slightly out of shape. I am not over weight, I am within healthy ranges for my BMI, but I am trying to lose 10lbs. Every time after I jog, I cough and wheeze and have a tightness in my chest. I feel that I get tired out more easily than others. Today, while running (not jogging) I began to feel out of breath and I could not run for more than 2 minutes without returning back to a walking pace. I tried to push myself to do more, and my throat/chest felt very tight and my finger nails turned blue-ish in color. Am I just out of shape or is it asthma? Should I go to my family physician?
