What causes pain in the shoulder blades on the upper back?

The most common cause of pain in the back around the scapula is local myofasciitis, an aseptic inflammation caused by prolonged overuse, traction, irritation, or cold exposure, leading to soreness in the upper back and scapular region. Treatment may include local heat application to promote blood circulation and facilitate the absorption of inflammatory exudates. It is important to get adequate rest, minimize local irritation, and avoid cold exposure in daily life, which can effectively relieve symptoms.
