Last week I woke up with a bit of a dry cough. It was there all morning and I assumed it was my asthma playing up. After lunch I helped the PiLs with something that exposed me to lots of dust and cat hair (trigger for my asthma). Predictably, cough was soon hacking and I was wheezing.
By the evening though, I had absolutely no energy, felt dizzy / faint, little appetite etc. I was diagnosed with the asthma in my early 30s and have not had a very bad flare up, just the odd day, so I didn't know if this was as a result of my asthma or not.
The next day, I had no energy at all, everythng was way too much effort, alternating chills and sweats, mildly raised temp, couldn't eat, just wanted to sleep, aching joints and muscles. Climbing the stairs was truly like climbing Everest and I wanted Oxygen half way up 
. This exhaustion lasted until Monday (6 days), then just lifted.
I didn't have much sneezing, runny nose etc, so I'm confused. All I have left is a very bad cough, and I still feel quite tired after a little effort.
So was this a bad asthma attack or was it flu as MiL thnks? I remember my Mum had the adage that if you thought there was a £20 note on the doorstep, if you could go get it, it was a cold, and if you couldn't it was flu. I would not have shifted for less than several thousand
