Pain between the shoulder blades is rarely caused by spine problems and usually stems from muscle strain, according to neurologist Rustam Bagautdinov.
Speaking to Russian news outlet Lenta.ru, Bagautdinov, a rehabilitation specialist at the Tri Sestry clinic, explained that sharp, pulling, or aching discomfort in the upper back is a widespread issue for individuals who spend long hours driving or working at computers.
He noted that the discomfort primarily originates in the muscles and fascia when they remain under continuous tension without adequate rest.
Fascia is a band of connective tissue that encloses and stabilizes muscles and internal organs throughout the body. When muscles in the upper back are kept in a static position for extended periods, such as while staring at a smartphone or desktop monitor, they suffer from lack of movement and reduced blood flow.
Over time, this persistent strain can trigger localized tightness, painful muscle knots known as trigger points, and a sharp sensation often described as a stake driven between the shoulder blades. Bagautdinov said this discomfort can also radiate outward into the neck or shoulders.
Role of sleep posture and pillows
Sleep posture also plays a critical role in maintaining upper back health, according to the specialist. Using a pillow that is too high forces the neck into constant forward flexion, whereas a pillow that is too low causes hyperextension.

Bagautdinov stated that both extremes create an uneven distribution of physical load, which extends into the shoulder girdle and the space between the shoulder blades.
Proper spinal alignment during sleep requires supporting the natural curvature of the neck. While incorrect bedding alone may not start the condition, Bagautdinov emphasized that poor sleep ergonomics frequently perpetuates existing muscle tension brought on by a sedentary lifestyle or lack of physical activity.
Underlying medical conditions
Although muscle strain is the most common trigger, Bagautdinov cautioned that interscapular pain can sometimes signal more severe underlying medical issues. Degenerative changes in the thoracic spine, irritation of intercostal nerves, and shoulder joint diseases can all produce similar symptoms.
In some instances, pain between the shoulder blades may even originate from internal organ pathology, where visceral pain is referred to the upper back region.
The thoracic spine consists of twelve vertebrae in the middle back that connect to the rib cage. Intercostal nerves branch out from the spinal cord through these vertebrae, and any inflammation or compression along these pathways can mimic muscular discomfort.
Because the sources of upper back discomfort vary widely, Bagautdinov emphasized that physicians must evaluate more than just the location of the pain.
He said medical professionals need to examine how the pain first developed, what specific movements or postures worsen it, and whether it occurs alongside any secondary symptoms before determining an accurate diagnosis and treatment plan.
