For the past several months and approx. 90% of the month, I have experienced hoarseness that comes on midday. I don't do excessive talking at my work, I am not a smoker nor am I around smokers, but by midday my voice is sounding strained and by late afternoon it will be almost gone. The next morning it is okay, but again by midday, the hoarseness starts all over. I have not had a cold, been diagnosed with allergies, do not have a sore throat,etc.
Can anyone tell me what might be causing this?
