Frozen shoulder is a common condition that affects the shoulder joint, which can cause pain and limit movement and range of motion. However, it is not the only condition that can cause shoulder pain and stiffness, and it is often misdiagnosed.
Rotator Cuff Injury
Rotator cuff injuries are a common cause of shoulder pain and stiffness. These injuries occur when the tendons and muscles that connect the shoulder joint become overstretched or torn, and can be caused by repetitive movements or a sudden, traumatic event. Symptoms of a rotator cuff injury include pain when reaching for objects, difficulty lifting the arm, and limited range of motion.
Bursitis
Bursitis is an inflammation of the bursae, which are small sacs of fluid that cushion the bones, muscles, and tendons in the shoulder joint. Bursitis can be caused by repetitive movements, overuse of the joint, or direct trauma. Symptoms of bursitis include pain when moving the shoulder, swelling, and stiffness.
Arthritis
Osteoarthritis and rheumatoid arthritis are two types of arthritis that can cause shoulder pain and stiffness. Osteoarthritis is a degenerative joint disease that can cause pain, stiffness, and swelling, while rheumatoid arthritis is an autoimmune disorder that can cause inflammation in the joints. Both types of arthritis can cause decreased range of motion and difficulty with everyday tasks.
Fibromyalgia
Fibromyalgia is a chronic condition that affects the muscles and connective tissues throughout the body, and can cause pain, stiffness, and fatigue. Fibromyalgia can cause pain in the shoulder joint, as well as throughout the body. Symptoms of fibromyalgia include widespread pain, fatigue, and difficulty sleeping.
It is important to seek medical attention if you are experiencing shoulder pain and stiffness, as these conditions can be difficult to differentiate without proper diagnosis. An experienced medical professional can help identify the cause of your symptoms and provide an appropriate treatment plan.
