Hi , and thanks for your post. While we cannot provide medical advice or diagnostics over the internet (for your own safety), your question does warrant a reply.
You are probably aware that asthma affects all patients differently. Not all patients exhibit the same symptoms nor are susceptible to the same triggers. How the flu, or general colds affect folks with this condition can vary as well.
For many, a simple cold or an episode of the flu may trigger the condition. Still, for others the affects may be negligible. The circumstances can vary widely among folks with this condition.
Based on your post, it sounds like you may have experienced an asthmatic exacerbation following contracting the flu. How were you able to manage the exacerbation, ? Is there anything you are able to share with the community at this time?
Wishing you the best,
Leon (site moderator asthma.net)
