Swollen Upper Abdomen
Another way to know whether you have mononucleosis is to check the upper abdomen area. Due to inflammation caused by the virus, this part can become swollen and tender. You can feel this by pressing on the upper left area of the abdomen. As soon as you notice the symptom, it is important to avoid sports or physical activities. Any trauma to this part would cause the internal organs, especially the spleen to become ruptured. Contact your healthcare provider immediately when you have sharp and sudden abdominal pain. [9]
