I have been sick for a week. It started with a cough and sore throat. The coughing got worse, especially at night. I was choking on flem or moucus. I went to my dr, and he said I had inflammation in my throat, but he was more concerned about my tachycardia, which was worse. My pulse was 118. He gave me Cipro. The past three days, I have loud rattling when I breathe, and my cough is still making me choke. My co-worker was just diagnosed with pneumonia, but I don t assume anything. I am very weak, no appetite, never had a fever, never had chills.what is your opinion?
