Shoulder Bursitis: Causes, Symptoms, Treatment, and Relief

Shoulder pain is one of the most common musculoskeletal complaints, affecting people of all ages and activity levels. What may start as a mild ache when reaching overhead can develop into persistent pain that interferes with daily activities, work, or sleep. 

One frequent cause of shoulder discomfort is shoulder bursitis, which occurs when the bursae, small fluid-filled sacs that cushion your shoulder joint, become inflamed.

What Is Shoulder Bursitis?

According to Cleveland Clinic, Shoulder bursitis is bursitis that affects your shoulder joint. The medical name for it is subacromial bursitis.

Generally, the shoulder contains multiple bursae, which act as natural cushions to reduce friction between bones, tendons, and muscles. When a bursa becomes inflamed, it causes bursa shoulder pain, limiting mobility and making even simple movements uncomfortable. The most commonly affected is the subacromial bursa, located beneath the top of the shoulder blade.

Shoulder bursitis can develop in different forms. 

• Acute bursitis appears suddenly, often after an injury or intense activity
• Chronic bursitis develops gradually due to repetitive stress. 
• Infectious (septic): This happens when an infection somewhere else in your body spreads to your shoulder bursae.

Rarely, bursitis results from bacterial infection, which requires urgent medical attention. Pain may worsen with overhead movements, lifting, or sleeping on the affected side, making early recognition important.

Symptoms of Shoulder Bursitis

Identifying bursitis shoulder symptoms early helps prevent progression and promotes faster recovery. Typical symptoms of shoulder bursitis include:

• Pain on the top or outer part of the shoulder: The discomfort often increases with overhead activity or lifting objects. This is the most common bursa pain shoulder complaint.
  
  
• Tenderness and swelling: Pressing on the affected area can cause noticeable tenderness and sometimes mild swelling.
  
  
• Limited range of motion and stiffness: The shoulder may feel tight or difficult to move, especially after rest.
  
  
• Pain at night: Many people notice that lying on the affected side exacerbates pain, disrupting sleep.
  
  
• Sharp flares with movement: Sudden motions can trigger intense pain, particularly in acute cases.

Understanding these signs of bursitis in the shoulder allows for early intervention before the condition becomes chronic.

Causes of Shoulder Bursitis

Shoulder bursitis occurs when the bursae, small fluid-filled sacs in the shoulder, become inflamed. This inflammation can result from repeated stress, improper shoulder mechanics, injury, or underlying medical conditions. Understanding the causes helps in prevention and effective management of the condition.

Repetitive Overhead Activity

Repetitive overhead movements, such as swimming, tennis, painting, or lifting heavy objects, place constant stress on the shoulder joint. Each time the arm moves above shoulder level, the subacromial bursa is compressed against surrounding tissues, gradually causing irritation and inflammation. 

Over time, this repeated strain can lead to chronic bursitis in shoulder symptoms, particularly in athletes, manual laborers, and people whose work or hobbies involve frequent overhead activity.

Poor Posture

Poor posture, such as slouching at a desk, leaning forward for extended periods, or carrying heavy bags on one shoulder, can alter the natural alignment of the shoulder joint. Misalignment increases friction on the bursa, which can lead to persistent irritation and inflammation. 

Over time, this can worsen bursa pain shoulder, reduce range of motion, and contribute to chronic stiffness and discomfort.

Injury or Trauma

Acute injuries, such as a fall, sudden twist, or awkward movement, can directly inflame the bursa. Trauma to the shoulder often triggers immediate swelling, sharp pain, and tenderness, limiting mobility. 

Acute cases typically result in more intense symptoms of bursitis in shoulder compared to gradual overuse injuries, and recovery may require rest and medical management.

Underlying Medical Conditions

Certain medical conditions, including arthritis, gout, and tendonitis, can increase inflammation in the shoulder joint. These conditions make the bursae more susceptible to irritation and can slow the healing process after minor injuries. 

As a result, people with these conditions may experience prolonged bursitis shoulder symptoms and recurrent flare-ups, especially with repetitive movements or strain.

Infection (Rare)

Although rare, bacterial infections can cause septic bursitis, leading to severe inflammation of the bursa. Infection-related bursa pain shoulder is usually accompanied by redness, warmth, swelling, and sometimes fever. Prompt medical attention is essential to prevent serious complications, including the spread of infection and joint damage.

How Shoulder Bursitis Is Diagnosed

Diagnosis typically begins with a physical examination. A healthcare provider assesses the shoulder for tenderness, swelling, range of motion, and pain patterns.

If needed, imaging may be ordered:

• X-rays: Check for bone spurs, arthritis, or other structural issues
• Ultrasound or MRI: Visualize soft tissue, including the bursae and tendons (Healthline)
• Blood tests or fluid sampling: If infection is suspected

These tests help distinguish symptoms of bursitis in shoulder from rotator cuff injuries, tendonitis, or arthritis. Early and accurate diagnosis ensures proper treatment.

Treatment for Shoulder Bursitis

Most shoulder bursitis cases improve without surgery. The primary goals of treatment are to reduce pain, control inflammation, and restore mobility.

Conservative Care

• Rest and activity modification: Avoid activities that exacerbate pain or strain the shoulder
  
  
• Ice therapy: Applying ice for 10–15 minutes several times a day helps reduce inflammation
  
  
• Over-the-counter medications: Ibuprofen or naproxen can alleviate pain and swelling.
  
  
• Physical therapy: Targeted exercises strengthen shoulder muscles, improve posture, and restore mobility
  
  

Medical Interventions

• Corticosteroid injections: Provide rapid relief of inflammation but frequency is limited to protect tendons.
  
  
• Prescription medications: Used for severe pain or persistent inflammation.
  
  
• Surgery: Rarely necessary and only considered after months of unsuccessful conservative management.

Exercises and Shoulder Mobility

Once pain begins to subside, gentle exercises can help restore mobility and prevent future flare-ups:

• Shoulder blade squeezes: Strengthen stabilizing muscles and reduce strain on the bursa
  
  
• Pendulum arm swings: Maintain range of motion without overloading the joint
  
  
• Light stretching: Helps relieve stiffness and improve flexibility
  
  

All movements should remain pain-free, as pushing through discomfort can worsen bursitis shoulder symptoms.

Sleep and Shoulder Pain

Nighttime pain is a major complaint for those with shoulder bursitis. Sleeping on the affected side can compress the bursa, intensifying discomfort and disrupting rest. Proper support and positioning are essential for recovery.
