Should i visit the doctor ?

See MD: You should visit a MD for a physical exam immediately. Your tonsils and lymph nodes being swollen with your fever would prompt a rapid strep test and rapid test for mononucleosis. A full medical history and exam is indicated. A review of other symptoms you are having is necessary, as well as your vital signs. Stay calm and see your MD, stay hydrated. Good luck.

Symptoms: Since you are 16 years old, please start by bringing this to your parents attention. Although this may be nothing more than a garden variety, upper respiratory infection - it would be important to rule out conditions like Strep Throat and Mono.
