Having general discomfort in throat due to mucus. I pressume its because of taking in so much cold liquids but it has persisted for about a week now. Couldn't sleep one night due to much discomfort and coughing - had to keep getting up to spit. Had been tested for HIV. 1st test returned 'not negative'. I doubted that so did at least three other tests which all came back negative. But still anxious.
