I had bronchitis in April of 2009. Since then I found I cannot sing anymore. My doctor who is treating me for a thyroid condition the last 15years says that I should see and ENT man so he can look down my throat at my vocal cords. I guess I am a coward. I do have allergies at night, as soon as I lay down to sleep I cannot breathe.
So maybe there is truth to getting rid of the duvet and changing the pillows. I will try that.
