Pain Between Your Shoulder Blades
Understanding Rhomboid and Upper Back Muscle Pain
WE-03 | Workspace Ergonomics series | DOXA Specialist Clinic
Pain between the shoulder blades can feel like a dull ache, a tight band, a tender knot or a sharp discomfort with movement. It often becomes more noticeable after long periods at a computer, driving, lifting or working with the arms held forward. The rhomboid muscles may be involved, but they are only one possible source of pain in this area.
This guide explains how the rhomboids and nearby upper-back muscles work, why desk habits may overload them, which changes may reduce strain, and when symptoms should be assessed rather than treated as a simple muscle problem.
The main point is that upper-back discomfort usually reflects a combination of load, reach, time and movement. A single posture is rarely the whole explanation. The aim is to reduce unnecessary effort and change position often enough that the muscles are not working continuously.
What the rhomboid muscles do
The rhomboid major and rhomboid minor lie beneath the trapezius. They run from the upper part of the spine to the inner border of each shoulder blade. They help draw the shoulder blades gently toward the spine and help control them while the arms move.
These muscles do not work alone. The trapezius, serratus anterior, rotator cuff, neck muscles and thoracic spine all contribute to shoulder-blade movement and upper-body control. This is why pain in the rhomboid region does not automatically mean that the rhomboids are injured.
Why desk work may cause pain between the shoulder blades
Reaching forward for the keyboard or mouse
When the keyboard or mouse sits too far away, the shoulder blades remain slightly forward while the arms reach. The upper-back muscles then work continuously to control the shoulder blades. A wide keyboard, cluttered desk or chair positioned too far from the work surface may create this problem.
Unsupported forearms
If the forearms are held above the desk without support, the muscles around the shoulders and shoulder blades carry more of the arms’ weight. Suitable armrests or light support from the work surface may reduce the demand, provided they do not force the shoulders upward.
One position held for too long
A comfortable position can still become uncomfortable when it is maintained for a long time. Concentrated work and back-to-back calls may reduce natural movement. The muscles may feel tired or stiff even when the workstation appears well arranged.
A screen or document placed off centre
Repeatedly turning toward a second screen, looking down at documents or twisting to use a telephone may create uneven loading. Symptoms may develop more on one side, especially when the same arrangement is used every day.
Work outside the office
Lifting, pulling, rowing, gym exercise, carrying bags and sudden twisting can also irritate the muscles between the shoulder blades. A true muscle strain is more likely after a clear overload or sudden movement and may cause pain, swelling, bruising or difficulty using the muscle.
What upper back muscle pain may feel like
Muscle-related pain is often felt along the inner border of a shoulder blade or across the upper back. The area may be tender to touch and may ache after sitting, reaching or using the arms. Some people feel a tight spot that changes with shoulder movement or gentle pressure.
Pain that eases when you change position, walk or move the shoulders may suggest that sustained loading is contributing. This pattern does not confirm a rhomboid strain. The thoracic spine, neck, ribs, shoulder joints and nerves can produce pain in the same region.
Seven practical changes to reduce upper back strain
1. Move closer to the desk. Position the chair so the elbows can stay near the sides. Avoid leaning forward to reach the keyboard, mouse or documents.
2. Keep the mouse beside the keyboard. Place it within easy reach and at about elbow height. Consider a compact keyboard if the number pad pushes the mouse too far outward.
3. Support the forearms lightly. Use correctly adjusted armrests or a stable work surface. The support should let the shoulders relax without pressing the wrists against a hard edge.
4. Centre the main screen. Place the screen directly in front of you and roughly an arm’s length away as a starting point. Increase text size if leaning forward is needed to read.
5. Reduce repeated twisting. Keep frequently used items close. Place documents near the screen and use a headset or speaker function when appropriate rather than holding a telephone between the head and shoulder.
6. Change position before pain builds. Take short, regular movement breaks. Stand, walk, change tasks or move the shoulders and upper back through a comfortable range.
7. Review workload and repetition. Equipment changes may not be enough if the task requires prolonged mouse use or leaves no opportunity to move. A workstation assessment can examine both the setup and the way the work is organised.
A gentle upper back reset
These movements are intended as comfortable position changes. They are not a treatment programme for a diagnosed injury.
· Let the arms rest and allow the shoulders to relax while taking three slow breaths.
· Roll the shoulders slowly backward and forward through a comfortable range.
· Gently draw the shoulder blades toward each other, hold briefly, then release. Do not force them down or squeeze hard.
· Sit upright and turn the upper body gently to each side without pushing into pain.
· Stand and walk for one or two minutes when it is safe to do so.
Stop if movement causes sharp pain, dizziness, shortness of breath, numbness, weakness or symptoms that spread around the chest or down an arm. Persistent pain needs assessment rather than increasingly forceful stretching or massage.
Comfort measures that may help
Continue normal activity as comfortably as possible and avoid guarding the upper back for the whole day. A wrapped warm pack or cold pack may provide short-term relief. Sleep, general activity and stress can also affect muscle tension and pain sensitivity.
If you are considering an over-the-counter pain medicine, ask a pharmacist or clinician whether it is suitable for you, especially if you have other medical conditions, take regular medicines, are pregnant, or have reacted to pain medicines before. Deep pressure or massage should not be used to mask worsening, unexplained or radiating pain.
When pain between the shoulder blades needs assessment
Arrange a clinical assessment if the pain is getting worse, lasts for several weeks, follows a fall or collision, repeatedly wakes you, limits normal activity, or is associated with a new rash. Seek prompt medical advice if you develop arm or leg weakness, numbness, tingling, difficulty walking, balance problems, unexplained weight loss, fever or a general feeling of illness.
Seek urgent medical care for sudden or severe upper-back pain with chest pressure or chest pain, shortness of breath, sweating, nausea, faintness, or pain spreading to the jaw or arms. New loss of bladder or bowel control, difficulty passing urine, or numbness around the buttocks or genital area also requires urgent assessment.
How DOXA Specialist Clinic can help
An assessment can determine whether the symptoms appear to arise mainly from muscle overload, the thoracic spine, the neck, the shoulder, a nerve or another condition. Management may include work modification, targeted physiotherapy, medication guidance, imaging or further investigation, depending on the examination.
