Lying down with chest pain 3 months after lumbar disc herniation foramenoscopy may be caused by rib compression, poor recovery, osteoporosis and so on. 1. Rib compression: when patients with lumbar disc herniation undergo traction surgery, the ribs may be compressed, resulting in chest pain. 2. Poor recovery: after lumbar disc herniation foramenoscopy, the situation is caused by poor postoperative recovery. 3. Osteoporosis: After herniated disc foramenoscopy, lying for a long time may lead to bone loss, causing osteoporosis, which may lead to the phenomenon of chest pain. When patients experience chest pain after lumbar herniated disc orbital surgery, it is recommended that they seek medical attention in time to be diagnosed by a professional doctor and given appropriate treatment.
