Wow, I'm so glad I found this site!
I was diagnosed with pleurisy 2 and a half weeks ago following a virus, a few weeks before, so naturally, as my asthma nurse has always told me, I've doubled up my Advair (or Seretide as it's called here in the UK!) for that entire time.
Previously I was taking one puff once a day in an evening which I never had any problems or side effects with, it just controlled my asthma really well. Now I'm taking 2 puffs twice a day (morning and night) and for a few days now I've been having terrible joint pains in my hands, feet, elbows and knees. Have been searching the internet for what it could be and think I might have found the answer! Hopefully if I decrease my meds back down the pain will improve!
Like a lot of people on here, though, I was NEVER told about any potential side effects to Seretide, just that it was a wonder drug.
