Shoulder pain may be caused by a problem in the shoulder joint or any of the ligaments, muscles or tendons that surround it. When you move your arm or shoulder, a shoulder pain that starts in the joint usually becomes worse.

The range of motion of the shoulder is quite broad and adaptable. When your shoulder is not working properly, it is difficult to move about freely and may create a lot of pain and discomfort.

The shoulder is made up of three primary bones: the humerus, clavicle or collarbone, and scapula/shoulder blade. A layer of cartilage protects and cushions the ends of these bones.

In terms of mobility, the shoulder joint is the most mobile joint in the body. It allows the shoulder to move forward and backward. When the arm is lifted and moved away from the body, it also allows for circular movement.

The shoulder range of motion is aided by the rotator cuff. The rotator cuff is made up of four tendons that connect to the shoulder joint. A tendon is a connective tissue band that connects a muscle to a bone. Raising your arm above your head may be unpleasant or difficult if the tendons or bones around the rotator cuff are injured or inflamed.

The diagnosis of shoulder pain includes MRI, CT scanning, and X-ray. Shoulder pain may often be addressed at home in many cases. In extreme cases of having severe shoulder pain, physical therapy, drugs, or surgery may be required.


The shoulder may be hurt as a result of heavy labor, sports participation, or just repetitive movement. There are a variety of disorders that might cause discomfort in the shoulder area. Conditions involving the cervical spine, as well as the liver, heart, and gallbladder, are factors associated with shoulder pain.

Shoulder difficulties become increasingly common as you get older, particularly around the age of 60. The soft tissues that surround the shoulder deteriorate with age increasing the occurrences of shoulder pain.

Shoulder pain may be brought on by a number of events and conditions. Rotator cuff tendonitis is the most common cause of right shoulder pain. This illness causes tendons to grow, making movement difficult.

Another common cause of shoulder discomfort and dysfunction is impingement syndrome, which occurs when the rotator cuff becomes stuck between the part of the scapula and the humeral head.

Shoulder pain is sometimes caused by an injury to another part of the body, most often the neck or the biceps muscles. In medical terms, this is known as referred pain.

The majority of shoulder disorders only affect a tiny portion of the shoulder and should go away fast.

Your shoulder pain, on the other hand, might be a sign of a more severe, long-term ailment like osteoarthritis or polymyalgia rheumatica, both of which are fairly common.

Patients with rheumatoid arthritis often have shoulder joint pain and edema. Shoulder osteoarthritis is less likely to harm them than other joints unless they have previously been injured.

There are a variety of additional probable reasons of shoulder pain, including the following:

Inflammation: When the shoulder becomes hot, red, and swollen as a result of an illness or injury, this is called inflammation. It is often associated with shoulder pain or sore shoulder.

Tension: Damage to the muscles and tendons surrounding the shoulder is referred to as tension. Tension in the muscles between the neck and shoulder is typically the consequence of poor posture and is frequently linked to how you stand or sit at work.

Bursitis: It is an inflammation of the bursa, a fluid-filled cushion between the shoulder bones that ordinarily permits muscles and tendons to move freely.

Arthritis: It is a common cause. Arthritis may wreak havoc on the bones and cartilage.

Other conditions due to which shoulder pain occurs include the following:

·         Dislocation

·         Arm bone fracture

·         Frozen shoulder

·         Radiculopathy i.e. pinched nerves

When to see a doctor

If you have a fever, persistent bruising, and are unable to move your shoulder or experiencing heat and discomfort around the joint, or if your pain continues after a few weeks of home therapy, see your doctor right away.

If your left shoulder pain comes on suddenly and is not due to an injury, call your doctor. This might be an indication of a heart attack.

If you suffer an injury to your shoulder along with a sharp pain in the shoulder and see blood, swelling, or exposed tissue, visit the nearest medical facility immediately.
