12 Common Causes of Pain in Shoulder and Arm

1. Rotator Cuff Injuries

One of the most prevalent causes of pain in the shoulder is rotator cuff injuries. This group of four muscles and tendons plays a vital role in shoulder stability and mobility.

Common causes of rotator cuff injuries include overuse, trauma, or gradual wear and tear. Symptoms may include pain, weakness, and limited range of motion.

Treatment for rotator cuff injuries varies based on the severity of the injury. For mild cases, rest, ice, and over-the-counter pain relievers can help alleviate discomfort.

Physical therapy is often recommended to strengthen the shoulder muscles and improve flexibility. In more severe cases, when conservative treatments are insufficient, corticosteroid injections or surgery may be considered to repair the torn tendons.

2. Shoulder Impingement Syndrome

Shoulder impingement syndrome, also known as subacromial impingement, occurs when the tendons of the rotator cuff become compressed between the shoulder blade and the head of the upper arm bone. This can lead to inflammation, pain, and difficulty lifting the arm.

The initial treatment for shoulder impingement syndrome involves rest, avoiding activities that exacerbate the pain, and using anti-inflammatory medications. Physical therapy plays a crucial role in restoring shoulder function and improving posture.

In cases where conservative methods do not provide relief, corticosteroid injections or arthroscopic surgery to decompress the shoulder joint may be recommended.

3. Frozen Shoulder (Adhesive Capsulitis)

Frozen shoulder, or adhesive capsulitis, results from the thickening and tightening of the shoulder joint capsule. It typically progresses through three stages, causing pain and stiffness, ultimately limiting shoulder movement. This condition often affects individuals between the ages of 40 and 60.

The primary goal in treating a frozen shoulder is to manage pain and improve shoulder mobility. Physical therapy, stretching exercises, and heat applications are commonly used to reduce stiffness.

In more severe cases, a doctor may perform joint distension to stretch the capsule or manipulation under anesthesia (MUA) to break up scar tissue and increase the range of motion.

4. Bursitis

Bursitis is an inflammation of the bursae, small sacs that cushion and reduce friction between tendons and bones in the shoulder joint. Repetitive movements, injuries, or underlying medical conditions can trigger bursitis, leading to localized pain and swelling.

The first step in treating bursitis is rest and avoiding activities that aggravate the condition. Ice packs and anti-inflammatory medications can help reduce inflammation and pain.

Physical therapy is beneficial for strengthening the shoulder muscles and preventing future flare-ups. In some cases, corticosteroid injections may be administered to relieve severe pain and inflammation.

5. Tendinitis

Tendinitis is the tendon’s inflammation, commonly caused by repetitive motions or overuse. When it occurs in the shoulder, it can result in pain and tenderness in the affected area.

Tendinitis treatment begins with rest, ice, and over-the-counter pain relievers. Physical therapy helps to improve tendon flexibility and strength.

In chronic cases, platelet-rich plasma (PRP) therapy or corticosteroid injections may be used to promote healing. Severe cases of tendinitis may require surgical intervention to repair the damaged tendon.

6. Arthritis

Arthritis is a chronic condition affecting various joints, including the shoulder. Shoulder arthritis may manifest as osteoarthritis or rheumatoid arthritis, causing pain, stiffness, and reduced range of motion.

Management of shoulder arthritis focuses on reducing pain and inflammation. Over-the-counter pain medications and nonsteroidal anti-inflammatory drugs (NSAIDs) can provide relief.

Physical therapy is essential for maintaining shoulder mobility and strength. In advanced cases, joint replacement surgery may be considered to alleviate pain and restore joint function.

7. Fractures and Dislocations

Injuries such as fractures or dislocations in the shoulder region can lead to severe pain in the shoulder and arm. Fractures are breaks in bones, while dislocations occur when bones are forced out of their normal positions.

The treatment for shoulder fractures and dislocations depends on the type and severity of the injury. Immobilization with a sling or brace is often necessary for proper healing.

In some cases, closed reduction may be performed to realign the bones without surgery. Severe fractures or dislocations may require surgical intervention to stabilize the joint.

8. Nerve Compression (Brachial Plexus Injury)

A brachial plexus injury involves damage to the nerve network that controls the shoulder, arm, and hand movements. Compression or trauma to the brachial plexus can cause pain, weakness, and numbness.

Treatment for brachial plexus injuries may involve physical therapy to improve muscle strength and coordination. In some cases, nerve grafting or nerve transfers may be considered to restore nerve function. Severe injuries may require surgical exploration and repair of the damaged nerves.

9. Cervical Radiculopathy

Cervical radiculopathy refers to a pinched nerve in the neck that can lead to pain, tingling, and weakness in the shoulder and arm. This condition is often caused by herniated discs or bone spurs in the cervical spine.

Non-surgical treatments for cervical radiculopathy include rest, physical therapy, and anti-inflammatory medications. In cases where conservative methods do not yield improvement, epidural steroid injections may be administered to reduce nerve inflammation.

Surgical options such as discectomy or cervical fusion are considered for severe or persistent cases.

10. Tendon Tears

Tendon tears in the shoulder, such as a biceps tendon tear, can cause significant pain and affect the arm’s strength and function. These tears can occur due to acute injuries or due to degeneration over time.

Treatment for tendon tears depends on the extent and location of the tear. Conservative treatments include rest, physical therapy, and anti-inflammatory medications. For severe tears, surgical repair may be necessary to reattach the tendon to the bone.

11. Heart-Related Conditions

In some cases, pain in the shoulder and arm may be a symptom of underlying heart-related conditions, such as angina or heart attack. It’s essential to seek immediate medical attention if you experience unexplained or severe pain in this region. Especially when accompanied by chest discomfort or shortness of breath.

Treatment for heart-related conditions causing shoulder and arm pain requires prompt medical attention. If diagnosed with heart-related issues, patients may receive medications to manage symptoms and reduce the risk of complications.

Lifestyle changes like a heart-healthy diet and regular exercise are essential for managing heart conditions.

12. Referred Pain

Referred pain is a phenomenon where pain in one part of the body is felt in another. This pain can occur due to issues in nearby structures, such as the neck or upper back, and may manifest as discomfort in the shoulder and arm.

The treatment for referred shoulder pain involves addressing the underlying cause. If the pain originates from the neck or upper back, physical therapy, chiropractic care, or massage therapy may help alleviate discomfort.
