Had asthma quite badly recently. It is now generally under control using Seretide, but have come down with a virus and chest just doesn't feel right. I have stopped sleeping and peak flow is down, but actual cough isn't too bad. Problem is that no one knows what causes my asthma and if I can't catch it in time it spirals out of control and takes weeks to recover from. Nurse told me to double my meds and start steriods which I have done, but feel a bit of a fraud as not really coughing or wheezing much. Does anyone else get like this? It has been mentioned as brittle asthma, but I know a lot of you have this and your symptoms are a lot more severe than mine. I just have no idea when mine will get worse!
