Arthritis – Osteoarthritis “wear and tear,” typically develops slowly – pain tends to increase over time. May notices pain, swelling, and stiffness of the joint.
Bursitis – A bursae are small, fluid filled sac that are located in joints throughout the body and act as cushions between the bones and the muscles, ligaments, and tendons that move over those areas. These bursae can become inflamed and swollen leading to pain which is typically worse with certain movements.
Tendinitis – A tendon connects muscle to bone. Tendinitis is the inflammation of these tendons and can be classified as acute or chronic.
Acute Tendinitis – typically associated with sports or work – caused by repetitive or excessive arm and shoulder movements – like a pitcher in baseball.
Chronic Tendinitis – typically associated with wear and tear over time or with degenerative arthritis.
Shoulder Tendinitis is most common in one of the four rotator cuff muscles and is also commonly seen on the Biceps Tendon (Long head).
Tendon Tears – The same tendons that were noted above can also be subject to tearing. Tendon tears can happened acutely with a sudden injury or happen slowly overtime with wear and tear.
Impingement – Impingement occurs with movement – when the arm is lifted out to the side, the scapula (shoulder blade) presses down and impinges upon the underlying soft tissue (bursa and tendons of rotator cuff). This impingement can cause limited movement of the shoulder, pain and inflammation of shoulder joint, bursitis and / or tendinitis.
