One of the reasons I decided to quit was to get fit again. So I got myself a fitness routine sorted out, starting off light, and doing it all properly. Part of the routine is to do some cardio 3 times a week (running for 15 minutes). I did my first run on Monday (second today), and I managed it fine. Ran for 15 minutes without coughing a lung up - woohoo!
Anyway, since then I've had a sore feeling in my chest, kind of llike what you get when you have a chest infection, but no problems with breathing, wheezing etc. In fact I haven't been able to breathe so well for years. I just wanted to know if the sore feeling was normal, especially after abusing my lungs for so many years.
