8. Fatigue and Weakness: The Lingering Shadows of Mononucleosis
For many, the profound fatigue that accompanies Infectious Mononucleosis is the most debilitating part of the illness. This isn’t ordinary tiredness; it’s an overwhelming, pervasive exhaustion that can significantly impair daily activities.
In Mononucleosis, fatigue is not just a symptom; it is often the dominant feature of the illness. For some patients, the fatigue is so severe that it can seem almost disproportionate to the other symptoms of the disease.
This fatigue can be both physically and mentally draining, affecting concentration and memory — sometimes referred to as ‘brain fog.’ It may linger for several weeks, and in some cases, for months after other symptoms have resolved.
Healthcare professionals usually emphasize the importance of rest and stress reduction to help patients recover. While antiviral medications are not typically used to treat Mononucleosis, a healthcare provider might consider them for patients with severe, lingering symptoms. (8)
