I really need to do something to improve my fitness levels but I don't know what to do. I am reasonably fit and play sport 4 hours a week and walk lots but when I try to run, or when I suddenly have to be active (including when I play sport), I get out of breath really quickly. I could walk for hours and be fine, but even a jog to the end of the street and I struggling for breath.
Initially I thought it was my asthma but I'm not sure, I mean sometimes it definitely is, but not always. If it's my asthma I feel tight chested, start coughing, get an itchy feeling inside my lungs and in my teeth (random) and it's relieved with salbutamol. Other times I'm just out of breath, it takes me a long time to recover breathing normally and it doesn't respond to salbutamol.
I always use my salbutamol before exercise and playing sport and I use seretide twice a day. This feeling of not being able to catch my breath is putting me off pushing myself as it scares me. The fear of my asthma is scary enough but at least I know salbutamol will help, even if I need 4-6 puffs to gain control.
Any suggestions? Is it just because I'm unfit?
