Back pain in children may be caused by incorrect sleeping position, trauma, intercostal neuralgia, etc. It is recommended to consult a doctor in time to find out the cause. 1. Incorrect sleeping position: If the child sits incorrectly while writing homework, or uses a cell phone or computer for too long, keeping a posture for a long time, it may lead to back pain. 2. Trauma: If a child’s body is subjected to external forces that exceed the capacity of the body’s soft tissues during sports or labor, it may lead to soft tissue injuries, and back pain will occur under the effect of trauma. 3. Intercostal neuritis: If your child catches a cold, suffers from a cold or is overworked, intercostal neuritis may be induced, resulting in pain in the child’s back, which is aggravated by coughing, deep breathing or sneezing. There may be other reasons for your child’s back pain, so it is recommended to consult a doctor in time to clarify the specific cause and treat accordingly if necessary.
