Fatigue, headaches and muscle soreness are common to Epstein-Barr infection, chronic fatigue syndrome and fibromyalgia, explains WebMD. Sleep troubles worsen fatigue in some cases of fibromyalgia and chronic fatigue syndrome. These two disorders may also cause increased urination, difficulty concentrating, nausea and gastrointestinal symptoms, and sensitivity to light, noises and cold. However, not all sufferers experience every symptom. Both chronic fatigue syndrome and the Epstein-Barr virus cause sore throat and swollen glands, says Centers for Disease Control and Prevention.
The cause of fibromyalgia is unknown as of 2015, although many experts think it is due to a combination of stressors on the body, explains WebMD. For many sufferers, chronic fatigue syndrome develops after a viral illness. While it is not necessarily triggered by a specific virus, scientists have studied the Epstein-Barr virus as a possible cause, notes Mayo Clinic.
Sufferers of chronic fatigue syndrome and fibromyalgia experience flare-up periods where symptoms are worse, reports WebMD. Treatments for both fibromyalgia and chronic fatigue syndrome often center on improving sleep and reducing pain due to muscle soreness or headaches.
Although infectious mononucleosis due to Epstein-Barr is a viral disease, there is no specific treatment for the virus. Antibiotics do not work against mono, so doctors recommend bed rest, over-the-counter medications to reduce pain and fever, and plenty of fluids, explains Mayo Clinic.
