Bursitis Shoulder and arm

Bursitis Shoulder and arm

Bursitis is a condition characterized by the inflammation of the bursa. A bursa is a small, fluid-filled sac that acts as a cushion between bones, tendons, and muscles, reducing friction and facilitating smooth movement. Bursitis can occur in various joints of the body, including the shoulder and arm.

When bursitis affects the shoulder and arm, it is typically referred to as shoulder bursitis or subacromial bursitis. The subacromial bursa is located between the rotator cuff tendons and the acromion, which is the bony projection of the shoulder blade.

Symptoms

The symptoms of bursitis in the shoulder and arm can vary from person to person but commonly include –

1. Shoulder pain – Bursitis typically causes pain in the affected shoulder. The pain may be a dull ache or a sharp, intense pain. It can worsen with movement or pressure on the shoulder.
2. Arm pain – The pain from shoulder bursitis can radiate down the arm, causing discomfort or pain in the upper arm or upper forearm.
3. Shoulder stiffness – Bursitis can lead to stiffness in the shoulder joint, making it difficult to move the arm freely. You may experience a limited range of motion and find it challenging to perform activities that involve overhead movements.
4. Swelling and tenderness – The affected area may become swollen, and there can be tenderness when touching or applying pressure to the shoulder or arm.
5. Warmth and redness – In some cases, the skin over the affected area may appear red and feel warm to the touch. This is usually a sign of inflammation.
6. Weakness – Bursitis can cause weakness in the shoulder and arm, making it challenging to lift or carry objects. You may notice a decrease in your usual strength and find tasks that involve arm movements more difficult.
7. Pain at rest – The pain associated with shoulder bursitis can persist even when you are at rest, particularly if the condition is severe or chronic.

Causes

The causes of bursitis in the shoulder and arm can be attributed to various factors. Some common causes include –

1. Repetitive overhead activities – Engaging in repetitive movements that involve raising the arm overhead, such as throwing a ball, swimming, painting, or lifting heavy objects, can put a strain on the shoulder joint and lead to bursitis over time.
2. Trauma or injury – A direct blow to the shoulder or a fall on an outstretched arm can damage the bursa, resulting in inflammation and bursitis.
3. Aging – As we age, the bursae in our joints may become less resilient and more prone to inflammation. This can increase the risk of developing bursitis.
4. Poor posture and ergonomics – Maintaining poor posture or engaging in activities with improper ergonomics, such as slouching or working at a desk with improper arm and shoulder support, can contribute to bursitis development.
5. Muscle imbalances and weakness – Imbalances in the muscles surrounding the shoulder joint, particularly the rotator cuff muscles, can disrupt the normal mechanics of the shoulder, leading to increased stress on the bursa and subsequent inflammation.
6. Rheumatoid arthritis and other inflammatory conditions – Chronic inflammatory conditions like rheumatoid arthritis can increase the risk of bursitis. 
7. Infection – In rare cases, a bacterial infection in the shoulder joint can lead to bursitis. This is known as septic bursitis and requires immediate medical attention.

Diagnosis and Tests

Diagnosing bursitis in the shoulder and arm typically involves a combination of a thorough medical history review, physical examination, and sometimes additional tests to confirm the diagnosis and rule out other possible causes of your symptoms. Here are some common diagnostic methods and tests –

1. Medical history and physical examination – Your healthcare provider will ask about your symptoms, when they started, and any activities or events that may have triggered them. They will also perform a physical examination, checking for signs of inflammation, tenderness, swelling, and range of motion in the shoulder and arm.

2. Imaging tests – In some cases, imaging tests may be ordered to visualize the structures in the shoulder joint and rule out other conditions. These tests may include –

• X-rays – X-rays can help identify other potential causes of shoulder pain, such as fractures, bone spurs, or arthritis. While they may not directly show bursitis, they can provide valuable information about the underlying structures.
• Ultrasound – Ultrasound imaging uses sound waves to create real-time images of the shoulder joint, including the bursa. It can help visualize inflammation and fluid buildup in the bursa.
• Magnetic Resonance Imaging (MRI) – An MRI scan provides detailed images of the shoulder joint, including the bursa, tendons, and surrounding structures. It can help identify inflammation, fluid accumulation, and any other underlying conditions.

3. Aspiration and analysis of bursal fluid – In some cases, your healthcare provider may perform an aspiration, where a needle is inserted into the affected bursa to withdraw a sample of the fluid. The fluid can then be analyzed for signs of infection, inflammation, or other underlying conditions.

Prevention

While it may not always be possible to prevent bursitis in the shoulder and arm, there are steps you can take to reduce the risk of developing the condition. Here are some preventive measures –

1. Practice proper body mechanics – Maintain good posture and use proper body mechanics when performing activities that involve your shoulder and arm. 
2. Take breaks and vary activities – If you engage in repetitive tasks or activities that place stress on your shoulder and arm, take regular breaks to rest and stretch your muscles.
3. Gradually increase activity levels – When starting a new exercise or physical activity regimen, gradually increase the intensity and duration over time. 
4. Warm up and stretch – Before engaging in any physical activity, warm up your muscles with gentle exercises and perform stretching exercises specifically targeting the muscles around the shoulder and arm. 
5. Strengthen the muscles – Regularly incorporate exercises that strengthen the muscles around the shoulder and arm, particularly the rotator cuff muscles. 
6. Use protective gear – If you participate in activities or sports that carry a higher risk of shoulder and arm injuries, such as contact sports or activities involving repetitive motions, wear appropriate protective gear, such as shoulder pads or braces, to provide additional support and cushioning.
7. Maintain a healthy weight – Excess weight can put additional strain on your joints, including the shoulder. 
8. Listen to your body – Pay attention to any early signs of discomfort or pain in your shoulder and arm. If you experience pain or feel overworked, take a break, rest, and give your body time to recover.

Treatment

The treatment of bursitis in the shoulder and arm typically involves a combination of self-care measures and medical interventions. Here are some common treatment options –

1. Rest – Rest the affected shoulder and arm to allow the inflamed bursa to heal. 
2. Ice and heat therapy – Applying ice packs to the affected area for about 15-20 minutes at a time, several times a day, can help reduce inflammation and relieve pain. 
3. Pain medication – Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help alleviate pain and reduce inflammation. 
4. Physical therapy – A physical therapist can provide specific exercises and stretches to improve the range of motion, strengthen the muscles around the shoulder, and promote healing. 
5. Steroid injections – In some cases, your doctor may recommend a corticosteroid injection into the bursa to reduce inflammation and alleviate pain.
6. Assistive devices – Depending on the severity of bursitis, your healthcare provider may suggest using assistive devices such as slings or braces to immobilize the shoulder and promote healing.
7. Surgical intervention – In severe or chronic cases of bursitis that doesn’t respond to conservative treatments, surgical removal of the inflamed bursa may be considered. This is typically a last resort option when other treatments have been unsuccessful.

It’s necessary to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan tailored to your specific condition. They can evaluate your symptoms, provide a proper diagnosis, and guide you through the most effective treatment options for your shoulder and arm bursitis.

Outlook

The outlook for bursitis in the shoulder and arm is generally positive with appropriate treatment and self-care measures. Most cases of bursitis can be successfully managed, leading to a reduction in symptoms and a return to normal activities.

With early diagnosis and prompt treatment, the inflammation and pain associated with bursitis can often be alleviated within a few weeks to a few months. However, the exact duration of recovery can vary depending on the severity of the condition, individual factors, and the effectiveness of the chosen treatment approach.
