Have spent the last week with a sore throat and a really annoying tickly cough that's doing my head in. I haven't felt specific asthma symptoms other than a heavy chest, BUT my peak flow has dropped from 550 to 450 (so nearly 80% of PB) I don't have an asthma action plan but after looking on the internet, if I did I'd be just about in the orange zone. Do I need to do anything?
Strangely I only just upped my Seretide from 125 2 puffs BD to 250 2 puffs BD as I was using little blue a lot, so I would have though this would have helped take my PF up?
