Hi everyone,

I'm putting up this post to gather some information from fellow asthmatics. I'm 26, 75 kg, and a long-time asthmatic... for many years (around ages 15 - 21) I was very inactive, smoked a lot, and did very little (or no) exercise. In recent years I've been trying to get fit and improve my overall health. I have a deviated septum which leads to a lot of mouth breathing and I take 1 puff of Symbicort (lowest dose possible) before I go to bed at night.

I started running in the gym and can now run for around 30 minutes if I take a single puff (power inhaler, terbutaline) before exercise. HOWEVER, if I don't take my inhaler before running, even for five minutes, I feel quite breathless and winded, my head feels quite 'poundy' and I feel quite weak. Is this typical for somebody who is asthmatic? I'm concerned I have some sort of heart problem, although I don't have chest pain or anything along those lines.

Many thanks everyone.
