3 weeks ago I had fever, chills, achy bones, heartache. His lasted 4/5 days. It went to my chest, very heavy, hard to breathe. I have been coughing up phlegm (dark yellow). The cough won t subside and I sleep all day and all night. I don t have an appetite and no energy. I went to the doc and was prescribed Clarithromycin and Triprolidine. I am allergic to penicillin. The doc heard some fluid and without having an X-ray, suggested it might be pneumonia. I am a very active person with no health issues and no smoker.
