Soreness and pain in the left shoulder blade area, radiating to the arm.
In general, soreness and pain in the left shoulder blade area that extends to the arm may be caused by factors such as muscle strain, shoulder periarthritis (frozen shoulder), or thoracic disc herniation. Specific analyses are as follows:
1. Muscle Strain
If one maintains the same posture for a prolonged period or engages in physically demanding labor, the muscles around the shoulder blade may become fatigued and sore. In severe cases, patients can go directly to the hospital and, under medical guidance, take medications such as nimesulide capsules or diclofenac sodium sustained-release tablets to relieve symptoms.
2. Shoulder Periarthritis (Frozen Shoulder)
This condition is an inflammation around the shoulder joint caused by damage to the rotator cuff tendons, with pain radiating to the shoulder blade region. Patients may, under a doctor's advice, take nonsteroidal anti-inflammatory drugs (NSAIDs) short-term to alleviate pain. Commonly used medications include ibuprofen sustained-release tablets and etoricoxib tablets.
3. Thoracic Disc Herniation
The protruding disc may compress spinal nerve roots at the exit of the neural foramen, causing pain along the intercostal and scapular regions. Patients can seek treatment at a hospital through cervical traction, physical therapy, or acupuncture. In severe cases, timely surgical intervention may be necessary.
Besides the above, similar symptoms may also be related to cervical disc protrusion, cervical osteophyte formation, rib fractures, and other conditions. It is important to visit a hospital early for appropriate examinations and tests to determine the exact cause and receive proper treatment. Additionally, attention should be paid to maintaining correct posture during sitting, standing, walking, and sleeping, and performing appropriate stretching exercises regularly to prevent recurrence or worsening of symptoms.
