Final answer:
Joint pain with a palpable mass may signal conditions like tendinitis or arthritis, commonly due to overuse or autoimmune issues, and can sometimes require surgery.
Step-by-step explanation:
Persistent, nontraumatic joint pain accompanied by a tender mass may suggest an underlying condition like tendinitis, arthritis, or a connective tissue disorder. These issues can stem from overuse or repetitive motion, leading to inflammation and degradation of the joint and surrounding tissues, and in severe cases, may even require surgical intervention to repair damaged tendons or cartilage.
For instance, professional or avid athletes often experience tendinitis, such as tennis elbow or swimmer's shoulder, due to repetitive stress on specific joints. Arthritis, which can be a product of aging, autoimmune disorders, or other causes, presents with joint pain and stiffness, and may be indicated by X-ray findings or clinical examination. Lastly, a palpable mass in or around a joint could be a sign of chronic infectious arthritis, particularly in those with underlying health conditions or who are immunocompromised.
