I know some people have complained of GERD from steroids (both nasal and inhaled). I think this might be happening to me. I've had some serious heartburn in the last few months, and I've sworn off the Rhinocort and Advair.

My throat feels irritated frequently, but it comes and goes. I noticed it was worse after the Rhinocort.

these things can also cause fungal infections of the nose.

as far as muscle pain goes... have you been taking anything other than the nasal steroid? Drugs like Cipro, Levaquin, Avelox, Tequin, can cause serious muscle and joint pain.
