Hi guys. I'm new to the site and after a bit of advice on any experiences with a chest infection kicking the asthma into overdrive. I'm guessing my infection is viral cos the different antibiotics I've been on haven't shifted it. How long do you reckon a viral infection should last? This one is still with me after a fortnight giving me a peak flow of 250 at best. The ventolin eases it a little, along with the seretide however playing my golf at weekends is becoming more of a chore than enjoyment.
