Hi, I have had asthma since I was about 9 years old and I am 18 now. About two years ago, I experienced a few attacks that put me in the ER a few times. I was put on a steroid inhaler called symbicort since. This last few months I have been wanting to take myself off this steroid because I hate the way it makes me feel. I was wondering what the common side effects are? I have dizzy spells, sharp pain in the left side of my chest, and on occasion trembling in my hands, are any of these common?
