after an upper respiratory cold/allergy my voice would feel strained by the end of the day. Now my mouth tastes sour and tasting food is different. I had a dr look in my throat and he said my vocal cords looked good. I still have some mucus in the back of my throat left over from being sick. It started Sept 30
Hiany disease has the side effect of altering the taste. The Chat Doctor.  An upper respiratory cold/allergy alters the taste more. As the doctor has told after examination that you cord look good, so there is nothing to worry in this case. And mucus that you are talking about definitely may take time to resolve. The altered taste and mucus both will go off with time. Thus, in my opinion there is nothing to worry about yet in such a case.
