Shoulder blade pain can be frustrating, especially when it affects how you sit, work, sleep, breathe, or move your arm. Some people describe pain under the shoulder blade as a dull ache. Others feel a sharp, stabbing pain below or behind the shoulder blade.
Pain in this area can come from several different sources. Sometimes it is a muscle or posture issue. Other times, it may be related to the neck, upper back, ribs, shoulder joint, or nerves. Before jumping into treatment, it helps to understand what may be causing the pain and what signs should prompt you to get evaluated.
“When someone comes in with pain under the shoulder blade, the goal is not just to calm down that one painful spot. We want to understand what is driving it, how it is affecting their day, and what they need to get back to, whether that is working comfortably, sleeping better, exercising, or just moving without thinking about it.”

Understanding the Shoulder Blade
The shoulder blade, also called the scapula, plays an important role in how your upper body moves. It connects with the upper arm and collarbone, and it works with muscles, tendons, ligaments, ribs, and the upper back to support shoulder and arm motion.
Because the shoulder blade is connected to several areas of the body, pain under the shoulder blade does not always start in one obvious place. It can come from the muscles around the scapula, irritation from the neck or upper back, shoulder mechanics, or less commonly, referred pain from another area.
Common Causes of Pain Under the Shoulder Blade
1. Muscle Strain or Overuse
Strenuous activity, poor posture, repetitive lifting, or long hours at a desk can strain the muscles that attach around the shoulder blade. Over time, this can lead to soreness, tightness, or aching under the scapula.
Signs to watch:
- Soreness that feels worse with movement
- Aching that improves with rest
- Tightness around the upper back, shoulder, or neck
- Pain after lifting, reaching, typing, or exercising
2. Poor Posture
Sitting hunched over a desk, looking down at a phone, or spending long hours in one position can place extra stress on the upper back and shoulder blade muscles. What we see a lot is that the painful area may be under the shoulder blade, but the driver may be how the neck, shoulders, and upper back are loaded throughout the day.
Physical therapy can help by looking at the full pattern, including posture, strength, mobility, and daily habits that may be contributing to the pain.
3. Nerve Irritation or Impingement
Pain under the scapula can sometimes be related to nerve irritation. This may happen when nerves are irritated or compressed around the neck, upper back, or shoulder region. Conditions such as a herniated disc or thoracic outlet syndrome can sometimes refer symptoms into the shoulder blade area.
Signs to watch:
- Tingling or numbness
- A deep ache near or under the shoulder blade
- Pain that travels into the arm or hand
- Weakness or heaviness in the arm
If symptoms include numbness, weakness, or pain that continues to spread, it is worth getting evaluated instead of waiting it out.
4. Referred Pain from Internal Organs
Less commonly, pain under the shoulder blade may come from an internal issue, such as gallbladder problems or heart-related concerns. This is not the most common reason for shoulder blade pain, but it is important to take it seriously. In some cases, shoulder pain may be referred from another area of the body.
Seek immediate medical attention if shoulder blade pain comes with symptoms such as chest pain, shortness of breath, nausea, sweating, dizziness, or unexplained severe pain.
5. Shoulder Impingement Syndrome
Shoulder impingement can happen when the tendons of the rotator cuff become irritated or compressed during shoulder motion. This may cause pain around the shoulder, upper arm, or shoulder blade area.
This can be more common in people who do a lot of overhead activity, such as swimming, throwing, lifting, painting, or certain gym movements.
6. Rib Injuries or Thoracic Joint Dysfunction
Pain near or under the shoulder blade can sometimes come from the rib cage or thoracic spine, which is the upper and mid-back region. Stiffness, joint irritation, or a rib-related issue can create pain that feels like it is sitting under the shoulder blade.
Signs to watch:
- Pain with deep breathing
- Tenderness when pressing near the ribs or shoulder blade
- Pain with twisting or reaching
- A sharp or catching feeling in the upper back
7. Myofascial Pain or Trigger Points
Myofascial pain involves tight, sensitive areas in the muscle tissue, often called trigger points. These areas can create pain locally or refer pain into the shoulder blade region.
This type of pain often feels like a knot, deep ache, or tight band of muscle. It may feel better temporarily with massage or stretching, but it can return if the underlying movement, strength, or posture issue is still there.
What Pain Under the Right or Left Shoulder Blade Can Mean
Many people search specifically for pain under the right shoulder blade or pain under the left shoulder blade. The side can matter, but it does not tell the whole story by itself.
Pain under the right shoulder blade may come from muscle strain, posture, rib or upper back irritation, shoulder mechanics, or referred pain. Pain under the left shoulder blade can come from many of the same causes.
The more important questions are:
- Did it start after a specific activity or movement?
- Is it sharp, dull, aching, burning, or stabbing?
- Does it change when you move your neck, shoulder, ribs, or upper back?
- Does it come with tingling, numbness, weakness, chest pain, nausea, or shortness of breath?
- Is it interfering with sleep, work, exercise, or daily activity?
Those details usually give a clearer picture than the side of the pain alone.
When to Seek Help for Shoulder Blade Pain
Mild shoulder blade discomfort may improve with rest, gentle movement, and changes to your daily posture or activity. But pain that keeps returning or limits your day should not be ignored.
Consider getting evaluated if you notice:
- Pain lasting more than a few weeks
- Difficulty moving your shoulder or arm
- Tingling, numbness, or weakness in the arm or hand
- Pain that affects sleep
- Pain that interferes with work, exercise, or normal daily activity
- Sharp or stabbing pain that does not improve
- Pain that keeps coming back after temporary relief
If you have chest pain, shortness of breath, nausea, dizziness, or sudden severe symptoms, seek immediate medical care.
How Physical Therapy Can Help Shoulder Blade Pain
Physical therapy can help by identifying what is actually contributing to the pain. Sometimes the problem is local to the muscles around the shoulder blade. Sometimes it involves the neck, ribs, upper back, rotator cuff, posture, or how the shoulder moves.
At B Physical Therapy, the first step is a full assessment of posture, range of motion, strength, movement patterns, and contributing factors. From there, treatment may include hands-on care, mobility work, strengthening, posture training, and guided exercises.
That matters because shoulder blade pain is often connected to real-life activities. It may show up when you sit at work, lift overhead, sleep on one side, train at the gym, run, swing a golf club, or pick up your child. The treatment plan should connect back to those goals.
Comprehensive Assessment
A physical therapist can look at your posture, shoulder motion, neck mobility, upper back mobility, rib movement, strength, and symptom behavior. This helps clarify whether the pain is likely coming from the shoulder, scapula, spine, ribs, muscles, or nerves.
Individualized Treatment Plan
No two cases of shoulder blade pain are exactly the same. A plan should be based on what is causing your symptoms, what makes them better or worse, and what you need to get back to.
Targeted Exercises
Exercises may focus on shoulder blade control, upper back mobility, rotator cuff strength, postural endurance, and flexibility. The goal is to help the area tolerate daily activity again, not just feel better for a few hours.
Manual Therapy
Hands-on treatment may help improve mobility, reduce muscle tension, and calm irritated tissues. This can be useful when paired with exercise and movement changes.
Posture and Ergonomic Training
If your shoulder blade pain is tied to long hours at a desk, phone use, driving, or repeated work positions, small changes to your setup and movement habits can make a difference. The goal is not perfect posture all day. It is helping your body handle the positions you spend the most time in.
Preventing Shoulder Blade Pain
While treatment can help once pain is already present, prevention matters too. A few simple habits can reduce strain on the shoulder blade area.
- Practice good posture: Avoid staying in one slouched position for long periods. Shift positions throughout the day.
- Stay active: Regular exercise helps maintain strength and mobility around the shoulder blades, neck, and upper back.
- Take breaks: If you sit or perform repetitive tasks for long periods, take short breaks to stand, stretch, or move.
- Use proper technique: During workouts, lifting, or sports, pay attention to form so the shoulder and upper back are not taking more stress than they should.
- Set up your workspace: Adjust your chair, monitor, keyboard, and desk so you are not constantly reaching, shrugging, or rounding forward.
Final Thoughts
Pain under the shoulder blade can be a minor irritation, but it can also become a recurring issue that affects sleep, work, exercise, and daily life. The cause may be simple muscle strain, but it can also involve posture, nerves, ribs, the neck, the upper back, or shoulder mechanics.
If your shoulder blade pain is not improving, keeps coming back, or is limiting what you can do, it may be time to have it evaluated.
