What causes sudden back pain between the shoulder blades on both sides, and what should be done about it?

The sudden pain in the upper back between the two shoulder blades may be caused by muscle strain, cervical spondylosis, gastroesophageal reflux disease (GERD), or other conditions. Medication should be selected based on the specific diagnosis. Detailed analysis is as follows:

1. Muscle Strain

If you have recently engaged in intense shoulder or back exercises, it may lead to muscle fatigue or strain, resulting in pain. Symptoms usually improve with adequate rest.

2. Cervical Spondylosis

Cervical spondylosis refers to degenerative changes in the cervical spine. Because the nerve roots of the cervical spine are interconnected with those of the scapular region, cervical spine abnormalities may affect the normal function of the scapular nerve roots, causing pain around the shoulder blades. Patients may take medications such as Jingshu Granules or Jingtong Pian according to medical advice.

3. Gastroesophageal Reflux Disease (GERD)

This condition occurs when stomach acid and digestive fluids flow backward into the esophagus. It results from dysfunction of the lower esophageal sphincter, which loses its normal ability to contract and relax, allowing gastric contents to reflux into the esophagus and throat, irritating the mucous membranes and causing pain. Patients may take medications such as enteric-coated rebamipide sodium capsules or omeprazole sodium bicarbonate capsules under medical guidance.

In addition to the above common causes, trauma, fasciitis, ankylosing spondylitis, and other diseases may also cause such pain. If discomfort occurs, timely medical evaluation and treatment are recommended to avoid delaying the condition.
