Shoulder Pain: Causes, Symptoms, Treatments and Tips

Posted On: March 18, 2026 by Robert Matijevich

Constantly sitting at a computer, infrequent physical activity, bruises and falls. Many people are familiar with aching, nagging, and sometimes sharp shoulder pain. Its great range of motion makes it much more susceptible to injury. Don’t tolerate pain! Let’s talk about effective shoulder pain exercise therapy.

Shoulder Pain Causes

To help you understand, we’ve compiled a detailed list of possible diagnoses that cause shoulder pain.

1. If the humerus is fractured, pain will inevitably be felt in the shoulder. This usually occurs due to a fall or a strong blow.
2. A brachial plexus injury involves damage to the bundle of nerves that connect the spinal cord to the arm and shoulder. This injury can cause pain, numbness, weakness, or even paralysis of the arm.
3. Avascular necrosis occurs when the bone in the shoulder joint begins to die due to a temporary or permanent blockage of the blood supply. This leads to microcracks and joint destruction, causing severe pain.
4. The collarbone connects the shoulder blade to the rib cage, and a fracture causes sharp pain in the front of the shoulder, especially when attempting to raise the arm.
5. Cervical radiculopathy involves a pinched nerve in the neck. If a nerve in the cervical spine becomes pinched or irritated, pain can radiate down to the shoulder and shoulder blade.
6. A heart attack can also sometimes cause shoulder pain. This condition requires immediate attention! It is life-threatening.
7. A shoulder dislocation is one of the most common injuries. The head of the humerus pops out of the socket. This is extremely painful, and the arm becomes immobile until the joint is reduced.
8. Impingement syndrome is a condition in which the tendons of the rotator cuff muscles become pinched between the bones when you raise your arm. This causes sharp pain, especially when raising your arm.
9. A muscle strain is a microtrauma to the muscle fibers caused by a sudden movement, heavy lifting, or excessive strain. “My shoulder hurts, but the pain usually goes away after a few days.”
10. Osteoarthritis is the wear-and-tear of joint cartilage that occurs with age. The cartilage thins, causing bones to rub against each other and leading to chronic pain and stiffness.
11. Polymyalgia rheumatica: This is an inflammatory condition that causes severe stiffness and pain in the shoulders and hips, especially in the morning. It is more common in people over 50.
12. Adhesive capsulitis involves the tissues around the shoulder joint thickening and tightening, as if in a corset. The shoulder becomes very stiff, making it difficult to lift or move behind the back.
13. Rheumatoid arthritis is an autoimmune disease. The immune system attacks the joint lining, causing inflammation, swelling, and pain, often symmetrically.
14. A clavicle separation often occurs after a fall on the shoulder, causing pain in the upper arm. Septic arthritis is a severe infection of the shoulder joint. It causes severe swelling, redness, heat, and excruciating pain. It requires immediate hospital treatment.
15. Sprains also cause shoulder pain. Unlike muscle strains, ligament injuries can also cause joint pain and instability.
16. Tendinitis is an inflammation or irritation of the tendons—the thick fibers that attach muscles to bones. It usually occurs due to repetitive motion and causes pain with movement.
17. A tendon rupture is a much more serious injury than tendinitis. The tendon can partially or completely tear, often accompanied by sharp pain, weakness, and the inability to move the arm normally.
18. With thoracic outlet syndrome, the nerves or blood vessels in the space between the collarbone and the first rib are compressed. This can cause shoulder pain and numbness in the fingers.
19. A cartilage rupture is also more painful. A cartilaginous ridge runs along the edge of the glenoid cavity of the shoulder, making the joint deeper and more stable. If this cartilage is torn, pain, crunching, and a feeling of instability in the shoulder occur.

Is Shoulder Pain Always a Sign of a Heart Attack?

Of course, if you have shoulder pain, don’t panic right away. It doesn’t necessarily mean you’re having a heart attack. However, you should be aware of its signs so you can respond promptly and take care of yourself. If you suddenly experience severe shoulder pain (usually the left shoulder) accompanied by any of the following symptoms, call 911 immediately:

1. Pain radiating to the back, abdomen, arms, jaw, or neck
2. Dizziness or lightheadedness
3. Chest pain or pressure
4. Difficulty breathing or shortness of breath
5. Cold sweat
6. Nausea

Is Neck and Shoulder Pain a Sign of COVID-19?

Muscle aches and weakness can indeed be symptoms of COVID-19. If you experience neck and shoulder pain along with other possible COVID symptoms, be sure to get tested and see a doctor.

Is Shoulder Blade Pain a Sign of Cancer?

We can reassure you that this is rare. A Pancoast tumor in the upper lung can indeed cause pain in the shoulder blade and upper back. The best way to resolve this issue is to consult a doctor.

The Best Shoulder Pain Treatment

Treatment depends on the specific cause of the pain. Your doctor may suggest various options. First and foremost, try to minimize strain on the affected side and avoid sudden movements. Your doctor may prescribe medications or ointments to relieve inflammation and pain. A chiropractor or physical therapist can help return the joint to its normal position, stretch the muscles, and restore flexibility. Sometimes, you may need to wear a sling or a special brace to rest the shoulder and promote healing. If the case is severe, surgery, including joint replacement, may be necessary. Your doctor will determine the appropriate treatment after making an accurate diagnosis.

Physical Therapy Treatment for Shoulder Pain

Physiotherapy is an effective way to relieve shoulder pain. It restores function, reduces discomfort, and prevents recurrence. First, a physiotherapist examines the underlying causes of the pain, which may include rotator cuff injuries, impingement syndrome, adhesive capsulitis, or postural disorders. The physiotherapist will assess the patient’s range of motion, strength, and joint mechanics, and analyze movement patterns to identify imbalances. Based on this assessment, the specialist develops a personalized plan. In the early stages, the doctor focuses on pain modulation and protecting damaged tissues. Ice or heat can sometimes be helpful, as well as gentle manual therapy techniques to mobilize stiff joints and relax tense muscles, as well as activity modification training to avoid painful movements while maintaining function.

As acute pain subsides, the therapeutic approach shifts toward corrective exercises and functional restoration. The specialist helps the patient restore proper mechanics to the entire shoulder joint, including the scapula (humerus) and surrounding musculature. The patient may begin with isometric exercises to engage the muscles without joint movement, then progress to isotonic exercises with resistance bands or light dumbbells. Key areas of focus include strengthening the rotator cuff muscles to stabilize the humeral head and strengthening the scapular stabilizers to create a stable base for arm movement. At the same time, therapists use neuromuscular rehabilitation to correct abnormal movement patterns and a comprehensive stretching program for tight structures, such as the pectoralis minor.

What Can You Do at Home to Get Relief?

If the pain is mild, you can manage it at home with a simple rule:

• Don’t move your arm unnecessarily. Apply ice or something cold to the painful area. If there is swelling, avoid applying heat to the shoulder—it will only make it worse.
• You can use an elastic bandage for support. Try to keep your arm elevated.
• You can take a pill (ibuprofen or paracetamol), but follow the instructions carefully.

If your doctor has given you the okay, gently stretch the muscles if movement doesn’t cause severe pain. You can gently massage your shoulder to relax it.

Conclusions

Home remedies like rest and ice are great for minor bruises or strains. But if the pain doesn’t go away, comes back, or interferes with your sleep and work, it’s time to seek professional help.
