Thanks, but that doesn't appear to be the case. The taste comes and goes also. It isn't constant.

I also have that problem. I have noticed it happens after or during a flare usually in my neck area. I think the sinus are being clogged and when they drain we feel as if we have an infection. I also feel like i could have an ear infection from time to time but i also think its the from the flares. Good luck hope you feel better soon.

For about a year now ever since i got a bad upper respitory infection i cough all the time, but latwly iv been coughing up stuff that tastes like infection. I totally understand. It tastes so gross like nothing else i know of. Very distinct.

This may sound silly, but could you check if you have tonsil stones, or little white soft aggregates of bacterial and cellular debris in the back of your throat. They can smell and taste bad.
