Joint problems refer to issues that affect the joints, which are the areas where two or more bones meet. Common conditions include arthritis, bursitis, and tendinitis. These problems can cause pain, swelling, stiffness, and reduced mobility, making it difficult to perform everyday activities. Several factors can contribute to joint problems, including age, injury, and obesity. Inflammation is often a key factor, leading to discomfort and decreased function. Treatment options may include medication, physical therapy, and lifestyle changes to help manage symptoms and improve joint health.
