12 Common Causes of Shoulder Pain on the Right Side

1. Rotator Cuff Tendinitis

One of the most common causes of right shoulder pain is rotator cuff tendinitis. The rotator cuff is a group of four muscles and tendons that help stabilize and move your shoulder joint. When these tendons become inflamed or irritated, it can lead to pain, stiffness, and limited range of motion.

Rotator cuff tendinitis is often caused by repetitive overhead motions, such as those involved in sports like tennis, swimming, or baseball. It can also result from poor posture or overuse of the shoulder muscles.

2. Rotator Cuff Tear

While tendinitis involves inflammation of the rotator cuff tendons, a tear is a more severe injury. Rotator cuff tears can range from partial to complete, and they can occur due to acute trauma (like a fall) or gradual wear and tear over time.

If you have a rotator cuff tear, you may experience severe pain, weakness, and limited mobility in your right shoulder. In some cases, you may even notice a bulge or deformity in the affected area.

3. Frozen Shoulder (Adhesive Capsulitis)

Also known as adhesive capsulitis, frozen shoulder is a condition characterized by stiffness and severe pain that limits the range of motion in your shoulder joint. It typically develops gradually, and the exact cause is often unknown.

A frozen shoulder can be particularly frustrating because it can take several months or even years to fully resolve. However, with proper treatment,  you can regain mobility and reduce pain.

4. Shoulder Impingement

Shoulder impingement occurs when the tendons of the rotator cuff become pinched or compressed between the acromion (the bony protrusion at the top of your shoulder) and the humerus (upper arm bone). This can lead to inflammation, pain, and limited range of motion.

Impingement is often caused by repetitive overhead activities or poor posture, and it can be exacerbated by bone spurs or other structural abnormalities in the shoulder joint.

5. Shoulder Bursitis

Bursae are small, fluid-filled sacs that cushion the areas where muscles and tendons glide over bones. When these bursae become inflamed, it’s called bursitis. In the shoulder, bursitis can cause pain, swelling, and stiffness, particularly when you move your arm away from your body.

Shoulder bursitis is often caused by repetitive motions, injury, or conditions like rheumatoid arthritis or gout.

6. Osteoarthritis

Osteoarthritis is a degenerative joint disease that can affect any joint in the body, including the shoulder. As the cartilage that cushions the joints wears down, it can lead to pain, stiffness, and limited mobility.

While osteoarthritis is more common in older adults, it can also occur in younger individuals. This is especially those who have sustained a previous injury or have a family history of the condition.

7. Shoulder Dislocation

A shoulder dislocation occurs when the ball of the upper arm bone (humerus) becomes dislodged from the shoulder socket (glenoid). This can happen due to a traumatic injury, such as a fall or a direct blow to the shoulder, or as a result of a congenital condition or previous injury that makes the joint unstable.

Dislocations are often accompanied by severe pain, swelling, and deformity in the affected area. Prompt medical attention is necessary to reset the joint and prevent further damage.

8. Shoulder Separation

While a dislocation involves the ball of the humerus being displaced from the socket, a shoulder separation occurs when the ligaments that connect the collarbone (clavicle) to the shoulder blade (scapula) are torn or stretched.

Shoulder separations are often caused by a direct blow to the shoulder, such as in contact sports or during a fall. They can range in severity from a mild sprain to a complete separation of the bones.

9. Pinched Nerve (Cervical Radiculopathy)

In some cases, right shoulder pain may not originate from the shoulder joint itself but rather from a pinched nerve in the neck or upper back. This condition, known as cervical radiculopathy, can cause pain, numbness, or tingling that radiates down the arm and into the shoulder.

Pinched nerves can be caused by herniated discs, bone spurs, or other spinal abnormalities that put pressure on the nerve roots.

10. Heart Attack

While it may seem counterintuitive, right shoulder pain can sometimes be a symptom of a heart attack, particularly in women. This is because the pain from a heart attack can radiate to the shoulder, arm, or jaw.

If you experience right shoulder pain accompanied by chest pain, shortness of breath, nausea, or sweating, it’s crucial to seek immediate medical attention, as these could be signs of a life-threatening condition.

11. Gallbladder Disease

In some cases, right shoulder pain can be a symptom of gallbladder disease, such as gallstones or cholecystitis (inflammation of the gallbladder). This is because the gallbladder and the right shoulder share a nerve pathway, and pain can be referred from one area to the other.

If you experience right shoulder pain along with nausea, vomiting, or abdominal pain, it’s important to consult your healthcare provider to rule out gallbladder issues.

12. Lung Cancer or Other Lung Conditions

While it may seem surprising, right shoulder pain can sometimes be a symptom of lung cancer or other lung conditions, such as pneumonia or pleurisy (inflammation of the lung lining). This is because the nerves that supply the shoulder and arm can be affected by tumors or other abnormalities in the lung.

If you experience persistent right shoulder pain along with other symptoms like coughing, shortness of breath, or weight loss, it’s important to seek medical attention for proper diagnosis and treatment.

Finding Relief: Treatment Options for Right Shoulder Pain

Now that we’ve explored the potential causes of right shoulder pain, let’s discuss some treatment options that can help you find relief:

1. Rest and Activity Modification

One of the first steps in managing right shoulder pain is to give your shoulder a break from the activities. Avoid any movements or actions that aggravate the pain, and allow your shoulder time to rest and recover.

It’s important to strike a balance between rest and gentle movement. While complete immobilization can lead to stiffness and further complications, excessive activity can also exacerbate the injury. Your healthcare provider or physical therapist can guide you on the appropriate level of activity.

2. Cold and Heat Therapy

Applying cold or heat to your right shoulder can help alleviate pain and reduce inflammation. Cold therapy, such as using an ice pack or a cold compress, can be particularly effective in the early stages of injury or flare-ups. The cold temperature helps constrict blood vessels, reducing swelling and numbing pain.

Heat therapy, on the other hand, can help relax the muscles and improve blood flow, which can aid in the healing process. Heat can be applied using a heating pad, warm compress, or even a warm shower or bath. However, it’s important to avoid excessive heat, as it can increase inflammation and potentially cause further damage.

3. Over-the-Counter Medications

For mild to moderate shoulder pain, over-the-counter medications like acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs) can provide relief. These medications can help reduce inflammation and alleviate pain, allowing you to continue with your daily activities.

4. Physical Therapy

Working with a physical therapist can be incredibly beneficial for managing right shoulder pain. A physical therapist can design a customized exercise program to help strengthen the muscles around your shoulder.

Physical therapy can be particularly helpful for conditions like rotator cuff injuries, frozen shoulder, or shoulder impingement syndrome. The exercises and techniques used in physical therapy can help restore range of motion, improve posture, and prevent further injury.

5. Corticosteroid Injections

In some cases, your healthcare provider may recommend a corticosteroid injection to help reduce inflammation and alleviate pain in your right shoulder. These injections can be particularly effective for conditions like bursitis or tendinitis.

Corticosteroid injections work by delivering a powerful anti-inflammatory medication directly to the affected area. While they can provide significant relief, it’s important to note that the effects are temporary.

Additionally, there is a risk of side effects, such as skin discoloration or tendon weakening, so these injections should be used judiciously and under the guidance of a healthcare professional.

6. Arthroscopic Surgery

If conservative treatments fail to provide relief, arthroscopic surgery may be an option for addressing certain shoulder conditions. This minimally invasive procedure uses small incisions and specialized instruments to repair or remove damaged tissues within the shoulder joint.

Arthroscopic surgery can be used to treat conditions like rotator cuff tears, labral tears, or shoulder impingement syndrome. During the procedure, the surgeon inserts a small camera (arthroscope) and surgical instruments through the incisions to visualize and repair the damaged areas.

7. Open Surgery

In more severe cases or when arthroscopic surgery is not an option, open surgery may be necessary. This can involve procedures like rotator cuff repair, shoulder joint replacement, or other surgical interventions.

Open surgery is typically more invasive and involves larger incisions than arthroscopic procedures. It may be recommended for severe rotator cuff tears, advanced arthritis, or complex fractures.

8. Lifestyle Modifications

Making certain lifestyle changes can also play a crucial role in managing right shoulder pain. This may involve adjusting your posture, modifying your daily activities, or incorporating stress-reduction techniques into your routine. By addressing the underlying factors contributing to your pain, you can help prevent further injury and promote long-term healing.

Improving posture can help reduce strain on the shoulder muscles and joints. This may involve making adjustments to your workstation.

Modifying your activities may involve avoiding or limiting movements that exacerbate your shoulder pain, such as overhead lifting or repetitive motions. Incorporating stress-reduction techniques like meditation, yoga, or deep breathing exercises can also help manage pain by reducing muscle tension and promoting relaxation.

Prevention and Self-Care Tips

While some causes of right shoulder pain may be unavoidable, there are several steps you can take to help prevent or manage this condition:

  • Maintain Good Posture: Poor posture can put unnecessary strain on your shoulder muscles and joints, increasing the risk of injury or pain. Be mindful of your posture when sitting, standing, or engaging in activities.
  • Strengthen Your Shoulder Muscles: Incorporating shoulder-strengthening exercises into your routine can help support the joint and reduce the risk of injury. Consult with a physical therapist or personal trainer for guidance on appropriate exercises.
  • Warm Up Before Exercise: Properly warming up before engaging in physical activity can help prepare your muscles and joints for the demands of exercise, reducing the risk of injury.
  • Use Proper Technique: When participating in sports or activities that involve overhead motions, be mindful of your technique to avoid putting excessive strain on your shoulder joint.
  • Take Breaks and Stretch: If you engage in repetitive motions or activities that involve your shoulders, be sure to take frequent breaks and stretch to prevent overuse injuries.
  • Maintain a Healthy Weight: Excess weight can put additional stress on your joints, including your shoulders. Maintaining a healthy weight through a balanced diet and regular exercise can help reduce this strain.
  • Manage Stress: Stress can contribute to muscle tension and inflammation, which can exacerbate shoulder pain. Incorporate stress-management techniques like meditation, yoga, or deep breathing exercises into your routine.

By following these prevention and self-care tips, you can help reduce your risk of developing right shoulder pain and manage any existing discomfort more effectively.

Exercises for Shoulder Pain on the Left or Right Side

Shoulder Stretch: Perform this exercise a total of 10 times.  Squeeze your shoulder blades together and hold for five seconds, then pull your shoulder blades forward and hold for five seconds.

Door Presses: Standing in a doorway, put your arm out directly in front of you, and place the back of your wrist against the door frame.  Push your arm against the door frame holding for five seconds. Repeat this action ten times before moving onto your other arm.

Door Rest: Once again, standing in a doorway, lift both hands above your head on either side of the door entrance.  Slowly lean forward, using your arms to support you until you feel some tension in your shoulders.  Hold for a maximum of 30 seconds before repeating four more times.

When to Seek Medical Attention?

While some cases of right shoulder pain may resolve with self-care measures, there are certain situations where it’s important to seek medical attention:

  • If you experience severe pain, swelling, or deformity in your shoulder
  • If your pain persists for more than a few days or worsens over time
  • If you have difficulty moving your arm or shoulder
  • If you experience numbness, tingling, or weakness in your arm or hand
  • If your pain is accompanied by other concerning symptoms, such as chest pain, shortness of breath, or fever

Your healthcare provider can perform a thorough evaluation, order diagnostic tests if necessary, and recommend the appropriate treatment plan to address the underlying cause of your right shoulder pain.
