When To Call a Doctor

If you have been diagnosed with mono, seek care immediately if:

  • You have severe pain in the upper left part of your abdomen. This may mean that your spleen camera.gif has ruptured. Rupture of an enlarged spleen caused by mono is rare. It is most likely to happen because of a blow to the abdomen.4
  • Your tonsils become so swollen that you find it difficult to breathe or swallow.

If you have not been diagnosed with mono and you have a severe sore throat that has lasted longer than 2 to 3 days after trying home treatment, call your doctor in 1 to 2 days.

  • Get plenty of rest.
  • Gargle with salt water or use throat lozenges to soothe your throat.
  • Take nonprescription pain relievers to reduce fever and relieve a sore throat and headaches.
  • Avoid contact sports and heavy lifting for 4 weeks after you become ill with mono (or until a doctor tells you it is okay). Mono can cause your spleen to enlarge, and these activities can increase your risk for injuring your spleen.
