What is Shoulder Pain?
Shoulder pain is discomfort or pain that occurs in or around the shoulder joint, which is the largest joint in the body. The shoulder joint is a complex joint that consists of several bones, muscles, tendons, and ligaments that work together to provide a wide range of motion.

What are the causes of shoulder pain?
Shoulder pain can be caused by a variety of factors, including injury, overuse, and age-related wear and tear. Common causes of shoulder pain include rotator cuff injuries, frozen shoulder, bursitis, tendinitis, arthritis, and shoulder impingement.

What is Supraspinatus Tendinopathy?
Supraspinatus tendinopathy is a condition that affects the supraspinatus tendon, which is one of the tendons that make up the rotator cuff in the shoulder. The supraspinatus tendon attaches the supraspinatus muscle to the shoulder blade and helps to lift and rotate the arm.

Tendinopathy refers to any condition that affects a tendon, including inflammation, degeneration, or tearing. Supraspinatus tendinopathy can result from overuse or injury and can occur in individuals of all ages, but is most commonly seen in individuals over the age of 40.

What are the symptoms of Supraspinatus tendinopathy?
Symptoms of supraspinatus tendinopathy may include pain and weakness in the shoulder, particularly when lifting the arm or performing overhead activities. The pain may be mild to severe and can limit range of motion in the affected shoulder.

What is subacromial subdeltoid bursitis?
A condition that affects the bursa sac located between the rotator cuff tendons and the acromion bone in the shoulder. The bursa sac is a fluid-filled sac that helps to reduce friction between the tendons and bones in the shoulder joint.

Subacromial subdeltoid bursitis occurs when the bursa sac becomes inflamed and swollen, causing pain and limited range of motion in the shoulder. This can result from overuse, injury (to rotator cuff tendons), or underlying medical conditions such as arthritis.

What are the investigations needed to diagnose Shoulder Pain?
There are several investigations that may be recommended to diagnose the cause of shoulder pain. These may include:

Physical examination: The doctor will assess the range of motion and strength of the affected shoulder, and look for any signs of swelling, redness, or deformity.

X-rays: This imaging test can help to identify any bone abnormalities or fractures in the shoulder joint.

MRI: Magnetic resonance imaging can provide a detailed view of the soft tissues in the shoulder joint, including the muscles, tendons, and ligaments.

Ultrasound: This imaging test uses sound waves to produce images of the shoulder joint and can help to identify any tears or inflammation in the tendons or bursae.

CT scan: This imaging test can provide a detailed view of the bones in the shoulder joint and can help to identify any abnormalities or fractures.

Blood tests: These tests may be recommended to identify underlying medical conditions, such as rheumatoid arthritis, that may be contributing to the shoulder pain.

The specific investigation or combination of investigations recommended will depend on the individual's symptoms, medical history, and the suspected cause of their shoulder pain.

How to treat Subacromial subdeltoid bursitis?

Treatment for subacromial subdeltoid bursitis may include rest, ice, and medications to manage pain and inflammation. Physical therapy and corticosteroid injections may also be recommended to improve range of motion and reduce inflammation. In severe cases, surgery may be necessary to remove the damaged bursa sac. Early intervention and proper treatment can help to prevent further damage and improve outcomes for individuals with subacromial subdeltoid bursitis.

Now-a-days regenerative therapy like PRP (Platelet rich plasma) injection with the help of Ultrasound helps to identify the pathology and treat the source or the origin of the shoulder pain generator. It is side-effect free since platelets are isolated from patient’s own blood.
