Symptoms of Mononucleosis

Symptoms will vary among individuals. Some people experience mild symptoms of mono, while others can have very serious mono symptoms.
Perhaps the most distinguishing symptom of mononucleosis is enlarged glands or lymph nodes, especially in the neck, but also in the armpit and groin.
Another common mononucleosis symptom is fever. A temperature as high as 103ºF (39.5ºC) is not uncommon.
Other symptoms can include:
  • Lack of energy
  • Body aches
  • Chills
  • Loss of appetite
  • Sore throat
  • Tonsillitis
  • White patches on the back of the throat
  • Swollen spleen
  • Swelling around the eye
  • Mild liver tenderness
  • Rash.

Making a Diagnosis

In order to make a mononucleosis diagnosis, the doctor will usually ask a number of questions and perform a physical exam. Because mono symptoms can be very similar to other illnesses, doctors often recommend tests to find out exactly what the problem is. One of these tests is the monospot blood test.

There is currently no treatment to kill either of the viruses that cause the illness; therefore, treatment for mononucleosis is focused on providing relief of mono symptoms as the body fights the virus.
