I was wondering whether I had an allergy or something else. I sort of had a chronic cough going on maybe starting two months ago, no fever, mucus/pheglm, but not as much as now. Sometimes I would wake up with a white string of mucus in back of my throat . I m very paranoid that these might be std symptoms. I went to my primary doctor and they just prescribed me Claritin. I am currently waiting on the lab work to come in hopefully this week.
