Over the past 3 days I've been experiencing severe throat pain, fever, and headache?

Doctor or ER. This may be signs of an untreated strep throat which if untreated could lead to serious health issues. I would go to the doctor asap or and ER now and get checked and likely begin a course of antibiotics.

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. Read more...

Not necessarily. although need to be thought of, however there's fever and infection (the sore throat) and may be extensive bacteremia, which can spike the neutrophil count. How is she doing otherwise? the whole clinical picture is important, the first step is to exclude other causes such as drugs, (eg steroids?), repeat the test. look carefully at other cell lines, good history and physical exam are important.
