10 Key Warning Signs Of Tuberculosis

7. Swollen, Painless Lymph Nodes: Extrapulmonary Clues

While often associated with infection, persistently swollen lymph nodes, especially if painless and found in the neck, armpits, or groin, can be a crucial indicator of extrapulmonary tuberculosis. This means the TB bacteria have spread beyond the lungs to the lymphatic system. Unlike typical infection-related swelling, these nodes may be firm and remain enlarged for weeks or months. This often-overlooked sign requires specific investigation, as it points to a systemic manifestation of TB that demands targeted diagnosis beyond simple chest imaging.

8. Profound, Unexplained Fatigue & Malaise: The Deep Exhaustion

Beyond everyday tiredness, tuberculosis can induce a profound, persistent fatigue and a general feeling of malaise that doesn't improve with rest. This isn't just lack of sleep; it's a systemic exhaustion caused by the body constantly fighting off the active bacterial infection, diverting energy resources to the immune response. If you experience debilitating weariness that seems disproportionate to your activities, a deeper investigation beyond common causes of fatigue is warranted, as your body might be silently battling a formidable foe.
