[59F] Experiencing systemic symptoms and abdominal discomfort

What might be happening

Based on the symptoms you've provided, which include fatigue, night sweats, fever, abdominal fullness, and a tender sternum, here are a few possibilities:

• Infectious Mononucleosis: Often caused by the Epstein-Barr virus, this condition can cause fever, fatigue, and night sweats. The spleen, located in the upper left abdomen, can become enlarged causing a feeling of fullness. The sternum can be tender due to swollen lymph nodes.

  • Treatment usually involves rest, hydration, and over-the-counter remedies to alleviate symptoms.

• Lymphoma: This is a type of cancer that affects the lymphatic system, which is part of the body's immune system. Symptoms can include fatigue, night sweats, fever, and a feeling of fullness in the abdomen due to enlarged lymph nodes or spleen. The sternum can be tender due to involvement of the chest lymph nodes.

  • Treatment typically involves chemotherapy, radiation therapy, and in some cases, stem cell transplant.

• Tuberculosis: This is a bacterial infection that primarily affects the lungs but can also affect other parts of the body. Symptoms can include fatigue, night sweats, and fever. Abdominal TB can cause a feeling of fullness in the abdomen.

  • Treatment involves a course of antibiotics over several months.

Remember, these are just possibilities and not a definitive diagnosis.
