Tuberculosis: A Contagious Bacterial Infection
Tuberculosis, commonly known as TB, is an infectious disease caused by bacteria that primarily targets the lungs. This bacterial infection triggers inflammation in the lungs, leading to a range of severe symptoms, including difficulty breathing, persistent coughing, and even coughing up blood. While TB typically affects the lungs, there are rare cases where the infection spreads to the bones, resulting in swelling in the hands or feet. It is worth noting that this bone-related manifestation usually occurs on only one side of the body.
Sickle Cell Disease: A Cause of Finger Swelling
Sickle cell disease is a severe condition known to cause finger swelling. Unlike the disc-like shapes of red blood cells found in most individuals, those with sickle cell disease have abnormal sickle-shaped or curved red blood cells. This abnormality is caused by alterations in hemoglobin, which impairs the cells’ ability to carry oxygen effectively. One of the initial symptoms experienced by individuals with sickle cell disease is dactylitis, a condition characterized by inflammation and swelling of the fingers. This symptom is particularly common among children, with records indicating that blocked blood flow to the fingers resulting in hand and finger swelling may manifest as early as six months of age. Dactylitis is known to cause intense pain, further highlighting the seriousness of sickle cell disease.
