I was on advair for about 2 months, suddenly I started to get severe chest pains, trouble breathing and tightness in the chest. I have asthma and my Dr prescribed me singuliar to take with it. I stopped the advair and went to my Dr today and he said he thinks advair did cause problems but thinks the chest pains are caused by my anxiety with the asthma issues since I haven't had asthma since I was a kid... I'm scared that the singulair may make my chest pains worse as they haven't gone away yet. Maybe I'm paranoid lol?
