What is under shoulder blade pain?

A muscular strain, commonly referred to as a pulled muscle, is a regular and typical cause of shoulder blade pain. Overuse or tension on the arms or upper back may be the cause of this. A muscle may also become strained if you just started a new exercise regimen, slept in a different posture, or tried a new bed.


Pain under your shoulder blade:-

The triangular bone that makes up the rear of your shoulder, the shoulder blade, can cause pain that can limit arm movement and interfere with daily activities.


This discomfort can range from being tender or achy across the shoulder or upper back to being acute or burning, such as between the spine and shoulder blade. Below, we address a few potential causes of this pain.


Causes of shoulder pain under the blade:-

  1. Poor posture:-

Sitting incorrectly for a long time might damage the structural makeup of your spine and lead to soreness below the shoulder blade.


When reading from a cell phone or working at a desk, for example, hunching your back, leaning your head down, or sitting to one side can weaken your muscles and put strain on your spinal discs, muscles, and ligaments. This common imbalance may be a factor in your upper back pain.


  1. Incorrect lifting methods:-

Without using adequate technique, lifting weight above your head puts your upper back and shoulders at risk of harm. You can put unnecessary pressure on your upper back if you lift anything that is too heavy or if the object is held away from the body with the spine out of alignment.


Overly heavy lifting can cause ligaments to sprain, muscles to get strained, and the spine or shoulder joint to become injured. Pain under or close to the shoulder blade may result.


  1. Overuse:-

Activities like painting a ceiling, helping friend move furniture, or playing softball can all exert greater strain on your upper back and shoulders than they are accustomed to.


Overuse can result in ligament sprains and muscle strains, which can hurt your upper back, particularly where your shoulder blade meets your spine.


  1. Cervical herniated disc:-

When a disc’s outer layer (annulus fibrosus) breaks and the inner layer (nucleus pulposus) begins to leak outward, this condition is known as a herniated disc in the cervical spine (neck).


The shoulder, arm, and/or hand may also experience pain from a disc herniation if an adjacent nerve root becomes inflamed. Pain near or into the shoulder blade region is more likely to be radiated by a disc herniation in the lower cervical spine.


  1. Dislocated rib:-

Although less often, reaching for something overhead or exerting repetitive strain can cause ribs to pop out of position or become misaligned. This action might cause sharp pain near your shoulder blade, which can occasionally make it difficult to take a deep breath.


  1. Heart problem:-

Some cardiac diseases might cause pain between the shoulder blades. For instance, aortic dissection, a dangerous, potentially fatal disorder, can produce excruciating pain that may go beneath or near the shoulder blade when the heart’s main artery is torn. Even more so in women, upper back and/or shoulder pain can be a sign of a heart attack.


  1. Compression fracture:-

When a vertebral bone (usually in your upper back) weakens and compresses, it results in back pain that gets better with rest or is tender to the touch. This condition is known as a compression fracture. In elderly adults, osteoporosis is the most frequent cause of compression fractures.


Shoulder pain when lifting arm:-


When you elevate your arm, a tendon (band of tissue) inside your shoulder may rub or catch on neighboring bone or tissue, resulting in shoulder pain. This condition is known as shoulder impingement.


It has an impact on the rotator cuff tendon, a rubbery structure that joins the shoulder-area muscles to the top of the arm.


If you experience discomfort or stiffness in your shoulder when you raise your arm above your head to brush your hair or when you reach behind your back, you may have a rotator cuff issue. Many of the things you wish to do, like place dishes in an upper cupboard, play tennis, or prune your garden, won’t be possible.



The humerus (the upper arm bone), the scapula (the shoulder blade), and the clavicle (the collarbone) are the three bones that make up your shoulder.


The rotator cuff helps to keep your arm in its place in the shoulder socket. The upper arm bone’s head is covered by these muscles and tendons, which also connect it to the shoulder blade.


The rotator cuff and the acromion, the bone at the top of your shoulder, are separated by a bursa, a lubricating sac. The bursa makes it possible for the rotator cuff tendons to move freely when your arm is raised.



One typical cause of shoulder discomfort is the rotator cuff. Pain may originate from:


  • It is possible to irritate or harm the rotator cuff tendons.
  • Pain may occur when the bursa is irritated and swells with more fluid.
  • The area between your acromion and rotator cuff becomes smaller as you elevate your arm to shoulder height. The bursa and the tendon may be irritated and painfully impinged upon by the acromion.



Both middle-aged persons and young athletes often have rotator cuff discomfort. Tennis, baseball, and swimming are three sports where young players are especially prone to injury.


People who do frequent lifting or above tasks with their arms, such as hanging paper, building, or painting, are also at risk.


An insignificant injury might also result in pain. It may sometimes happen for no obvious reason.



Localized swelling and discomfort in the front of the shoulder are often symptoms of rotator cuff pain. When you elevate your arm, you could feel discomfort and stiffness. When the arm is lowered from an elevated posture, there could also be discomfort.


Mild first symptoms are possible. Patients usually delay seeking therapy until later on. These signs might consist of:

  • Little discomfort that is felt both while moving about and when at rest
  • Pain extending down the side of the arm from the front of the shoulder
  • Sudden discomfort while lifting and reaching
  • Tennis ball throws or serves may cause discomfort for athletes in overhead sports.


As the problem progresses, the symptoms increase:

  • Evening pain
  • Weaker and less mobile
  • Difficulty buttoning or zipping garments, or doing other tasks that need the arm to be behind the back.

Shoulder tenderness may be quite acute if the discomfort appears quickly. There might be discomfort and restrictions on all motion.
