Hello, I have been on Symbicort for about a week. I also take Singulair at night. I have had 7 sinus surgeries, the most recent in April, 2015. My asthma has flared up with the recurrent infection in my sinuses, so we re trying the Symbicort because the pro-air wasn t working. I am now suffering from EXTREME fatigue, headache and I ve lost my voice. I m constantly clearing my throat. Is it from the Symbicort? (Note: It s not a sinus infection, I m well versed in them, unfortunately. I m not sick- don t feel sick. I feel tired and hoarse. These are all new since I started the Symbicort.)
