Shoulder soreness is something many of us brush off until it becomes a problem. Whether it’s a dull ache after a long day at work or a sharp pinch when reaching overhead, a sore muscle in the shoulder blade can point to deeper issues that need attention. At Cohen Trigger Point Therapy, we see this all the time, and the good news is that with the right approach, relief is within reach.

What is Shoulder Pain

Shoulder pain is a common problem that can disrupt anyone’s daily routine, whether you’re an athlete, an office worker, or a busy parent. The shoulder blade or scapula is a frequent site of discomfort and pain, in this area can make even simple tasks feel challenging. From muscle strain caused by overuse to poor posture developed over time, there are many reasons why you might experience shoulder blade pain. Understanding the root causes and treatment options is the first step to finding relief. In this guide, we’ll break down the most common causes of shoulder blade pain, what to watch for, and how to relieve shoulder blade pain, so you can get back to moving comfortably and confidently.

What Causes a Sore Muscle in the Shoulder Blade?

A sore muscle in the shoulder blade can develop for several reasons and pinpointing the exact cause is key to effective pain relief. Muscle strain is one of the most common culprits, often from lifting, reaching or sudden movements that overstretch the muscles that support the shoulder joint. Overuse, such as repetitive lifting or frequent overhead activities can also lead to muscle fatigue and soreness in the shoulder blade area. Poor posture—like slouching at a desk or hunching over a phone—puts extra stress on the muscles around the shoulder blade making them more prone to tightness and discomfort. Sometimes more complex issues like a rotator cuff tear or frozen shoulder can cause persistent pain and limited range of motion. Pain can also be referred from other parts of the body, such as the neck or even internal organs, so it’s important to consider all possibilities. Identifying the underlying cause of your shoulder blade pain is key to choosing the right treatment and finding lasting relief.

What Causes a Sore Muscle in the Shoulder Blade?

Shoulder Anatomy: The Basics

The shoulder is one of the most mobile and complex joints in the body making it both powerful and prone to discomfort. At its core the shoulder joint—known as the glenohumeral joint—is a ball and socket joint where the upper arm bone (humerus) fits into a shallow socket in the shoulder blade (scapula). The shoulder blade itself is a flat, triangular bone that provides a stable base for arm movement and supports the entire shoulder structure. Along with the collarbone (clavicle) these bones create a framework that allows for an impressive range of motion from reaching overhead to rotating the arm. The acromioclavicular joint which connects the clavicle to the scapula plays a crucial role in shoulder movement and stability; issues such as arthritis or injury in this joint can cause shoulder and shoulder blade pain and may require specific diagnosis and treatment. The surrounding muscles, tendons and ligaments work together to stabilize the joint and facilitate smooth movement. When any part of this system is strained—whether from poor posture, muscle overuse or a sudden muscle strain—it can cause shoulder blade pain or discomfort in the shoulder joint. Sometimes pain in the shoulder can even be referred pain from other areas, so it’s important to understand the underlying anatomy when seeking relief.

Poor Posture and Sedentary Habits

If you spend long hours at a desk or frequently look down at your phone, you’re not alone—and you’re likely putting strain on your shoulder muscles without realizing it. Poor posture, especially when prolonged, alters the alignment of your spine and shoulders, leading to muscle fatigue and soreness. Over time, this can result in nagging pain that persists and may not resolve with rest, highlighting the importance of addressing posture early. Trigger points often develop as the body tries to compensate for this imbalance.

Preventative Tip: At Cohen Trigger Point Therapy, we emphasize early posture correction and movement education to prevent long term dysfunction.

Overuse, Repetitive Motion or Muscle Strain

From athletes and weekend warriors to parents constantly lifting children overuse is a major cause of shoulder discomfort. Repetitive motion leads to tiny tears in the muscle fibers which can accumulate over time. These micro-injuries often lead to tightness, inflammation and—you guessed it—trigger points. Repetitive motion can also result in the formation of a muscle knot, a localized area of tight, tender muscle that causes pain and limits mobility

Expert Insight: Josh Cohen sees this in patients who ignore the early signs. Catching it early prevents deeper tissue damage and speeds recovery.

Sleeping in the Wrong Position

Do you wake up with shoulder pain? You may be sleeping in the wrong position. Sleeping on one side or using a pillow that doesn’t support your neck and shoulder alignment can compress muscles overnight and cause morning stiffness and soreness. A consistent pattern of poor sleep posture can irritate shoulder muscles and start a pain cycle. If not addressed this can get worse over time.

Pro Tip: Josh recommends trying different pillow heights and sleep positions for optimal shoulder alignment.

Stress and Muscle Tension

Stress doesn’t just affect your mood—it affects your body. Emotional stress often shows up physically as tight muscles, especially in the neck and shoulders. Over time, this chronic tension leads to sore muscles and the formation of trigger points. Stress can also cause a muscle spasm, which can contribute to shoulder pain.

Cohen Approach: Our holistic approach includes stress relief modalities that reduce both mental and physical tension.

Trigger Points and Myofascial Dysfunction

This is where we come in. Trigger points are tight, hypersensitive spots within the muscle tissue that can refer pain to other areas. In the shoulder they often radiate pain that’s hard to pinpoint. Myofascial dysfunction—a disruption in the muscle and fascia connection—amplifies this issue. Our targeted approach finds and releases these knots to restore mobility and relieve pain. Self massage techniques like using a foam roller or massage ball can also be done at home to manage trigger points.

Josh Cohen’s Take: “Trigger points are often silent until they’re not. Addressing them early is the key to long term relief.”

Heart Attack and Shoulder Pain: When Soreness Means Something Serious

While shoulder pain is often caused by muscle strain or poor posture it’s important to know when it means something more serious. In some cases pain in the shoulder—especially the left shoulder blade—can be a warning sign of a heart attack. This is because of referred pain where discomfort from the heart is felt in other areas like the shoulder, arm or upper back. If you have severe pain in your shoulder or left shoulder blade along with chest pain, shortness of breath or sudden difficulty breathing you need to get immediate medical attention. These symptoms may indicate acute coronary syndrome—a blockage of blood flow to the heart that requires urgent care. Don’t ignore warning signs—if your shoulder pain is accompanied by chest tightness, nausea or lightheadedness call emergency services now. Knowing the difference between regular shoulder pain and a heart attack can be life saving.

How to Relieve Shoulder Muscle Soreness and Shoulder Blade Pain

Apply Heat or Cold Strategically

Ice is best for reducing inflammation immediately after acute activity, heat is better for relaxing chronic tightness and improving blood flow. A warm compress, heating pad or hot shower can relax tension while a cold pack or other ice or heat source helps with swelling and fresh injuries.

Cohen Tip: If you’re not sure which to use we guide patients based on their specific condition and timeline.

Gentle Stretching and Mobility Exercises

Keep the shoulder joint mobile. Incorporate stretching exercises that gently open up the chest and shoulders like wall angels or doorway stretches. Regular stretching exercises are important for preventing muscle strain in the upper back and shoulder area. Strengthening core muscles can also support shoulder health by improving overall stability. For a more structured approach to recovery consider exercise therapy which involves working with a healthcare professional to develop a personalized regimen of physical activities and stretches. The goal is to loosen the surrounding musculature without pushing into pain. Mobility exercises maintain joint health and prevent recurrence.

Early Intervention Reminder: Movement is medicine—just make sure it’s the right kind, at the right time.

Massage and Trigger Point Therapy

Nothing beats skilled hands when it comes to releasing stubborn shoulder pain. At Cohen Trigger Point Therapy we use precise techniques to deactivate trigger points and improve circulation. Many patients notice a big difference in range of motion and pain relief within just a few visits. A physical therapist can also provide professional guidance for massage and rehabilitation techniques to ensure safe and effective recovery.

Real-World Example: One patient, a graphic designer, had full overhead mobility after just three visits using Josh’s customized myofascial release plan.

Improve Ergonomics and Daily Posture

Small changes can make a big difference. Adjust your workspace so your monitor is at eye level, your shoulders are relaxed and your back is supported. When driving or relaxing use lumbar and neck support to maintain alignment.

Preventative Focus: These posture changes are part of our long term prevention strategy at Cohen Trigger Point Therapy.

When to See a Physical Therapist

If you have sharp pain, numbness, significant loss of mobility or if you have pain that is persistent or severe don’t wait. Early treatment prevents chronic dysfunction and speeds up recovery. If you have ongoing symptoms or nerve compression occupational therapy may be recommended to help improve function and reduce discomfort. Cohen Trigger Point Therapy is designed for early intervention so you can address issues before they become chronic.

What to Expect During an Exam

If you see a healthcare provider for shoulder blade pain you can expect a thorough exam to determine the cause of your discomfort. Your doctor will start by asking you detailed questions about your symptoms including when the pain started, how bad it is and what activities make it better or worse. They’ll then assess your shoulder joint by checking your range of motion, muscle strength and reflexes. Specific tests like the shoulder blade squeeze help evaluate the function of the muscles and tendons around the shoulder blade. Your provider will also look for signs of referred pain such as tenderness or numbness in the arm or chest. If there’s any suspicion that your shoulder blade pain could be related to a heart condition additional tests like an ECG or chest X-ray may be ordered. In some cases you may be referred to a specialist for further evaluation. Be open and honest about your symptoms and medical history so your doctor can create the best treatment plan for your shoulder blade pain.
