What Causes Back Shoulder Blade Pain on the Right Side?

Pain in the right shoulder blade can be a common experience, affecting daily activities and overall comfort. The shoulder blade (scapula) is a triangular bone on the upper back that connects the collarbone to the upper arm, enabling shoulder movement. Pain in this area can stem from various sources, making it a complex symptom. This discomfort can arise from musculoskeletal issues, nerve irritation, or referred pain from internal organs.

Common Causes of Right Shoulder Blade Pain

Right shoulder blade pain often originates from musculoskeletal issues, linked to daily habits and physical activities. Overuse or strain of muscles around the shoulder blade, like the rhomboids and trapezius, can cause a dull ache or sharp twinge. Activities like lifting heavy objects, repetitive overhead reaching, or sleeping in an uncomfortable position can strain these muscles, causing localized pain.

Poor posture contributes to muscle strain in the upper back. Prolonged slouching, hunching over a desk, or looking down at a smartphone can weaken back muscles and put continuous stress on the network of muscles and ligaments supporting the shoulder blade. This sustained tension can result in chronic discomfort and may lead to conditions like “winged scapula,” where the shoulder blade protrudes abnormally.

Issues with the rotator cuff, a group of muscles and tendons stabilizing the shoulder joint, can refer pain to the shoulder blade area. While rotator cuff injuries primarily affect the shoulder, pain can radiate to the upper back due to the shoulder complex’s interconnectedness. Myofascial pain syndrome, characterized by sensitive points within muscles known as trigger points, can cause pain in seemingly unrelated areas, including the shoulder blade.

Nerve compression in the cervical (neck) or thoracic (upper back) spine is another source of pain radiating to the right shoulder blade. A herniated disc in the lower cervical spine or upper thoracic spine can irritate or compress nerves, leading to symptoms like stinging, burning, or electric-like pain, sometimes accompanied by numbness or tingling in the affected area.

When Pain Signals a Serious Condition

While many causes of right shoulder blade pain are musculoskeletal, this discomfort can indicate a more serious health issue, particularly when referred from internal organs. Referred pain occurs when an issue in one part of the body causes pain to be felt in another, due to shared nerve pathways.

Gallbladder issues, such as gallstones or inflammation (cholecystitis), are a common cause of referred pain to the right shoulder blade. Pain from the gallbladder is often described as sharp and can radiate from the upper right abdomen to the right shoulder blade or back, sometimes worsening after fatty meals. It may be accompanied by nausea, vomiting, or fever. Irritation of the phrenic nerve, which connects the diaphragm to the shoulder region, explains this.

Liver problems can manifest as pain in the right shoulder blade. Conditions affecting the liver, such as hepatitis or cirrhosis, can cause a dull, throbbing pain in the upper right abdomen that spreads to the right shoulder blade, back, and neck. This referred pain is attributed to the phrenic nerve, as the liver can stimulate nerves connected to the shoulder.

Less common lung conditions can cause pain in the shoulder blade area. Pleurisy, pneumonia, or certain types of lung tumors, like a Pancoast tumor, can lead to discomfort in the upper back or shoulder blade. They may also present with respiratory symptoms like coughing, shortness of breath, or fever.

Though less frequent on the right side, heart-related issues can cause referred pain to the right shoulder blade, especially in women. Angina or a heart attack might present with pain radiating to the back, neck, jaw, or shoulder blades, alongside chest pain, shortness of breath, sweating, or unusual fatigue. Immediate medical attention is necessary if these symptoms occur. Rare but serious conditions, including spinal tumors, fractures, or infections, can also cause persistent and worsening shoulder blade pain.

Certain “red flag” symptoms warrant immediate medical evaluation:
Sudden severe pain
Pain accompanied by shortness of breath
Chest pain
Fever or chills
Unexplained weight loss
Numbness, tingling, or weakness in the arm or hand
Changes in bowel or bladder function
Pain after trauma to the upper back

Effective Strategies for Relief

Managing right shoulder blade pain often involves self-care and professional interventions, depending on the cause. Resting the affected area and modifying aggravating activities can provide relief. Avoiding movements that worsen discomfort for a day or two allows muscles and tissues to begin healing.

Heat or cold therapy can alleviate symptoms. Ice packs can reduce acute inflammation and pain, used for 10-20 minutes with at least a two-hour break between applications. Heat, such as a heating pad or warm compress, can relax tense muscles and improve blood flow, applied for 15-20 minutes. Alternating between ice and heat can be beneficial.

Gentle stretching and exercise restore flexibility and strengthen surrounding muscles. Simple stretches for the neck, shoulders, and upper back, like neck rolls, shoulder rolls, or cat-cow stretches, can improve circulation and reduce muscle tension. Maintaining proper form and avoiding painful movements are important.

Improving posture is an important step in preventing and relieving shoulder blade pain, especially for those who spend long hours sitting. Practicing good posture while sitting, standing, and sleeping distributes stress evenly across the spine and muscles. Ergonomic adjustments to workstations, such as ensuring the computer monitor is at eye level, can significantly reduce strain.

Over-the-counter pain relief medications, such as NSAIDs like ibuprofen or naproxen, can reduce pain and inflammation. Acetaminophen can be used for pain relief. These medications provide temporary relief and should be used as directed. Topical pain creams can offer localized relief.

For persistent or severe pain, professional treatment may be necessary. Physical therapy involves assessing the pain’s root cause, followed by targeted exercises, manual therapy, and education on posture and body mechanics. A physical therapist can design a personalized program to strengthen weak muscles and stretch tight ones.

Chiropractic care may address spinal alignment issues, with adjustments improving joint mobility and reducing nerve irritation. Massage therapy can relieve muscle tension, spasms, and trigger points in the upper back and shoulder blade area, promoting relaxation and pain reduction. In some cases, medical interventions may be explored, including prescription medications like muscle relaxants or trigger point injections for localized pain. In rare instances, surgery may be necessary for structural problems like severe nerve compression or fractures that do not respond to conservative treatments.
