Asmanex Twisthaler 60 Dose and advair

I am 41 and recently diagnosed with asthma. 2 weeks ago was put on asmanex, 60 doses. and for the last week, have had serious joint pain. to the point i almost couldn't walk. i am an avid runner so this has been devastating. dr's reassured me it's not caused by the meds and i could have been exposed to 5th disease which has similar issues in adults. i have quit taking the asmanex to see if the pain goes away. has anyone else experienced this? i see alot of similar symptoms with advair so not sure what med i want to consider. i honestly feel worse now than i did a month ago before i knew i had asthma. any meds out there that don't cause pain??
