I suffered with asthma from the age of 11 up until about 18. Am currently 35 and have a had a nasty viral infection for the last few weeks. It has resulted in a an inflamed airway and a persistent night time cough. I visited the docs today and she says that the virus has aggravated my asthma symptoms and has given me a salbutamol reliever. I had a peak flow of about 340. My question is two fold really. Is it possible for the asthma to flare up after so many years with no symptoms and if so are they likely to stick once am fully over the virus?
