joint effusion

Joint effusion is the medical term for swelling in a joint caused by excess fluid buildup. This fluid may arise from inflammation, injury, or underlying conditions like arthritis. When the joint swells, it can feel tight, painful, and limit movement. Commonly affected joints include the knees, ankles, and elbows. Doctors may diagnose joint effusion through physical examination and imaging studies, and treatment options typically include rest, ice, compression, elevation, and sometimes medications or procedures to remove the excess fluid. It's important to address the underlying cause to prevent further issues.
