Joint pain can be described as pain, discomfort, or inflammation in any part of the joint, such as the muscles, tendons, ligaments, cartilage, or bone. In most cases, joint pain can be caused by arthritis or arthralgia, which causes pain or inflammation that originates inside of the joint itself. While these are the most common causes of joint pain, there are many others. A few other commonly known causes of joint pain, although not the full list of potential causes, are bone cancer, broken or fractured bone, bursitis, dislocation, fibromyalgia, gout, Lyme disease, lupus, sprains, tendinitis, and leukemia. Your doctor can potentially diagnose your joint pain following a physical exam or may send you to one of many potential specialists to perform additional tests to form a solid diagnosis. Examples of specialists who can treat joint pain include orthopedic doctors, rheumatologists, pain management specialists, podiatrists, and others who focus on specific joints of the body and conditions that can affect them.
