Step 4: Read and complete the decision guide to learn more about your symptoms.

Sore Throat

Some viruses will cause a more prolonged sore throat along with fever and body aches. Infectious mononucleosis caused by the Epstein-Barr virus can do this.

Contact your doctor.

Infectious mononucleosis is diagnosed by a blood test. If you have infectious mononucleosis, you will likely take a longer time to feel better. It may be several days to a couple weeks before you are ready to go back to school or work.

If mononucleosis is suspected, your doctor will carefully examine your spleen for signs of enlargement, a potential complication of "mono." If your spleen is enlarged, you will need to avoid contact sports for a few months to avoid serious injury to your spleen.
