Other symptoms that can occur with mono include:
- Swollen spleen
- Swelling around the eye
- Mild liver tenderness
Mono symptoms usually get better in one or two months, without any treatment. The sore throat and fever usually improve within two weeks, and the swollen lymph nodes within three weeks, although the improvement can vary. The most common symptoms that continue for the longest time are the tiredness and body aches. Most people can return to work or school after three to four weeks. Others may be exhausted and unable to return to their full activities for months.
It is also possible for complications of mono to occur. Although these complications occur infrequently, when they do develop, they can be dramatic. Mono is rarely fatal.
There are no known associations between mono symptoms and problems during pregnancy, such as miscarriages or birth defects.
As discussed in the eMedTV article Mononucleosis Causes, the Epstein-Barr virus (EBV) is the most common cause of the disease. This type of mono is called infectious mononucleosis. In 15 percent of cases, mono symptoms occur as a result of an infection with cytomegalovirus (CMV). This virus can cause slightly different symptoms. For a person who develops CMV mononucleosis, common symptoms of mono can include:
- High fever
- Body aches
- Joint aches
- Enlarged spleen.
Unlike infectious mononucleosis, CMV mononucleosis does not usually cause a sore throat or swollen lymph glands.
