Just reached a cold country. Had a fever and headache, now fever is gone but having cough and bad sore throat, currently coughing up brown phlegm.

URI. You are in the midst of an upper respiratory infection. The productive cough indicates there is moderate phlegm inside your lungs. Drink lots of water to help thin it out. Drink hot tea/honey for the cough and consider some cilantro (usually I do pico de gallo) to help bring up mucous. See an MD soon to make sure it's in recovery. http://www.pdrhealth.com/diseases/cough.
