How to tell the difference between tendonitis and arthritis?
Persistent pain, stiffness, and swelling around a joint can be worrying. Is it a temporary inflammation from overuse, or is it a chronic condition like arthritis? Two of the most common culprits are tendonitis and arthritis. While their symptoms can feel similar, they are fundamentally different conditions. What is Tendonitis? Tendonitis is the inflammation or irritation of a tendon – the thick, fibrous cords that attach muscle to bone. It’s typically caused by acute injury or, more commonly, repetitive micro-trauma (overuse). Key Characteristics of Tendonitis: Location of Pain: The pain is usually localized to a specific tendon and the immediate area around a joint. Cause: Repetitive motion or sudden, sharp injury. Common examples include “Tennis Elbow,” “Golfer’s Elbow,” or “Achilles Tendonitis.” Nature of Pain: Pain often worsens with specific movements or activities and improves with rest. You might feel a dull ache or a sharp pain when moving the affected limb. Stiffness: Stiffness may be present but is usually more pronounced after periods of inactivity and eases with movement. In short, tendonitis is often an overuse injury affecting the connective tissue near a joint. What is Arthritis? Arthritis is a broader term for conditions that cause inflammation within the joint itself. It involves damage to the joint cartilage (the cushioning surface at the end of bones) and other joint structures. The most common type is Osteoarthritis (OA), a “wear-and-tear” arthritis. Key Characteristics of Arthritis: Location of Pain: The pain originates from within the joint. Cause: Cartilage breakdown (Osteoarthritis), an autoimmune response (Rheumatoid Arthritis), or other systemic causes. Nature of Pain: A deep, aching pain is common. It can be persistent, even at rest or during the night. Stiffness: Joint stiffness, especially in the morning or after sitting for long periods, is a hallmark sign and can last for more than 30 minutes. Additional Symptoms: You may experience swelling, redness, warmth, and a reduced range of motion. In advanced stages, the joint may appear deformed. Essentially, arthritis is a joint-centric disease affecting the cartilage and bone. Key Differences at a Glance Feature Tendonitis Arthritis (Osteoarthritis) What’s Affected? Tendons (connects muscle to bone) Joint Cartilage & Lining Primary Cause Overuse, Repetitive Motion Wear-and-Tear, Age, Autoimmune Pain Location Localized around a tendon Deep within the joint Stiffness Improves quickly with movement Morning stiffness lasts longer Why an Accurate Diagnosis is Crucial ? Because the treatments for tendonitis and arthritis differ significantly, getting an accurate diagnosis is essential. While tendonitis often responds well to rest, ice, physiotherapy, and anti-inflammatory medication, arthritis management may require a more comprehensive approach, including lifestyle modifications, long-term medication, injections, or even joint replacement surgery in severe cases. Inamdar Hospital Pune offers a comprehensive Department of Orthopaedics. Their team of specialists utilizes advanced diagnostic tools to accurately differentiate between tendonitis, arthritis, and other conditions, creating a personalized treatment plan to relieve your pain and restore your mobility. Frequently Asked Questions (FAQs) 1. Can tendonitis turn into arthritis? Generally, no. They affect different tissues. However, chronic, untreated tendonitis can sometimes lead to joint degeneration over a very long period, but it is not a direct cause of arthritis. 2. What is the main difference between tendonitis and rheumatoid arthritis? Tendonitis is a localized overuse injury. Rheumatoid Arthritis (RA) is a systemic autoimmune disease where the body attacks its own joints, often affecting multiple joints symmetrically and causing fatigue and fever. 3. Does arthritis pain move around? In inflammatory types like Rheumatoid Arthritis, pain can “flare” in different joints. Osteoarthritis pain is typically confined to a specific, weight-bearing joint like the knee or hip. 4. How does a doctor diagnose tendonitis vs. arthritis? A doctor will perform a physical exam, review your medical history, and may use imaging tests like an X-ray or MRI to look at the joint and surrounding tissues. 5. Where can I find the best orthopaedic doctor in Pune? For expert diagnosis and treatment of joint pain, tendonitis, and arthritis, you can consult the specialists at the Department of Orthopaedics at Inamdar Hospital Pune.
