Are these advair side effects temporary or permanent? I have taken advair for 4-6 months usually taking it only once a day. I never felt like it helped me out. I started having chest discomfort, rapid heart rate, pounding chest (as if my heart woud explode), tingling and numness, tremors in my arms , legs and chest, restlesness at night, my blood pressure increased, fatigue and weakness. I have not taken it for 8 months but still have re occuring symptoms. Will this ever go away. I have lost my confidence in our doctors. I have read not to just stop taking advair, why is this?
