Severe lower back pain at 8 months pregnant, making it impossible to fall asleep

At 8 months of pregnancy, back pain severe enough to prevent sleep may be caused by physiological factors or pathological conditions such as lumbar muscle strain or lumbar disc herniation. Appropriate treatment should be based on the specific cause, with detailed analysis as follows:

I. Physiological Factors

Eight months into pregnancy falls within the third trimester. At this stage, the fetus is relatively large, and due to gravitational effects, abnormal pressure may be exerted on the lower back tissues and bladder, potentially causing severe back pain that interferes with sleep. This condition typically gradually improves after delivery.

II. Pathological Factors

1. Lumbar Muscle Strain

If a pregnant woman engages in excessive physical activity during this period, the back muscles may remain tense for prolonged periods, possibly leading to aseptic inflammation and resulting in lumbar muscle strain, which can cause the aforementioned symptoms. It is recommended to apply gentle massage or heat therapy to the lower back to relieve discomfort.

2. Lumbar Disc Herniation

If a woman already had lumbar disc herniation prior to pregnancy, increased pressure on the affected area during gestation may trigger a recurrence. The protruding disc can abnormally compress surrounding nerves and soft tissues, causing this symptom. It is advisable to engage in appropriate daily exercise and avoid不良 habits such as prolonged standing or sitting.

Besides the above, conditions such as scoliosis, rheumatoid arthritis, or ankylosing spondylitis could also be responsible. It is recommended to reduce intake of high-fat foods, maintain good personal hygiene, and keep emotional well-being.
