Arthritis and tendonitis can both cause intense pain, but they are two different conditions.
Arthritis is a common disorder that affects your joints. It can cause pain and inflammation, making it difficult to move or stay active. There are many types of arthritis. Each form causes different symptoms and may need different treatments. While arthritis usually affects older adults, it can develop in men, women and children of any age.
Tendinitis is a condition where the connective tissues between your muscles and bones (tendons) become inflamed. Often caused by repetitive activities, tendinitis can be painful. It commonly happens in the elbow, knee, shoulder, hip, Achilles tendon and base of the thumb. Tendinitis is also called tendonitis.
