I've been reading various bits and pieces of previous posts over the last while which mention this but I just wondered if as anyone in same position or can shed any light on this? . My peak flow readings vary very little despite major symptoms. I have almost always been 450 when well controlled and even during a lower lobe chest infection last year it stayed the same. Despite increased SOB and bouts of coughing in last ten weeks my peak flow still stayed steady at 450. I started to doubt it was asthma related until I had an acute attack last week (first ever). The next day I felt extremely poorly , coughing constantly and constantly SOB/wheezy however my peak flow had only dropped to 350 the lowest it’s every been. Makes me think perhaps I'm just very symptomatic for a relatively small drop in PF? I continued to feel really poorly , taking ventolin every 4 hours every day in last week since attack in conjunction with steroid inhaler, course of pred and started on montelukast too. Last 2 days PF has risen to 400 and I've started to feel a bit better but still symptomatic with cough, SOB etc. Chest infection has been ruled out (clear chest / normal x ray). So I guess I'm wondering if its possible for PF to remain quite good for some people during flares ups ie not always a good indicator?? It worries me because when I went to out of hours/ gp surgery / asthma nurse in the last ten days it's the first thing they ask me and its making me think they don't believe I've been that unwell as they seem to place such emphasis on it.
Help!
