Lower Back Pain from Sitting in an Office Chair

Lower back pain caused by prolonged sitting in an office chair can be alleviated through adjusting sitting posture, taking regular breaks, applying heat therapy, strengthening the back muscles, and using medications. Additionally, attention to lifestyle details is necessary to prevent recurrence.

1. Adjust Sitting Posture
   Maintaining the natural curvature of the lumbar spine is crucial. Choose a chair with a backrest, place a soft cushion at the waist or use an ergonomic lumbar support to keep the lumbar support against the lower back. Keep both feet flat on the ground with knees and hips at a 90-degree angle, avoiding prolonged slouching or leaning forward. Keep elbows naturally下垂 and level with the desk. Adjust your sitting posture every 30 minutes to reduce continuous pressure on the lower back from a single position.

2. Take Regular Breaks
   Sitting continuously for more than 1 hour can cause poor blood circulation in the lower back. It is recommended to get up and move for 3-5 minutes every hour, performing gentle movements such as waist rotations and side bends, or engaging in low-intensity activities like standing against a wall or walking to promote muscle relaxation and blood circulation.

3. Apply Heat Therapy
   For chronic strain-related lower back pain, apply a warm towel at around 40℃ to the lower back for 15-20 minutes, 2-3 times a day, to dilate blood vessels and accelerate the removal of metabolic waste. Gentle massage can enhance the effect. For acute sprains, cold compresses are required within 48 hours, followed by heat therapy later. Use physical therapy devices as directed by a doctor to avoid burns or excessive stimulation.

4. Strengthen Back Muscles
   Perform core muscle training such as the Superman, bridge, and plank exercises for 10-15 minutes each day. Swimming and the cat-cow pose in yoga can enhance the endurance of the back muscles and improve lumbar stability. Exercise gradually and avoid strenuous activities that may worsen injuries. Patients with osteoporosis need to adjust the intensity.

5. Use Medications
   When the pain is significant, non-steroidal anti-inflammatory drugs such as diclofenac sodium sustained-release tablets and celecoxib capsules can be used as directed by a doctor, or topical flurbiprofen gel patches can be applied. Patients with muscle spasms can take methocarbamol tablets in combination. Patients with osteoporosis need to take alendronate sodium tablets and other anti-osteoporosis drugs in combination. Exclude contraindications before taking medications and avoid self-medication.

To prevent recurrence, pay attention to lifestyle details: Maintain a regular schedule and avoid sitting for more than 2 hours at a time. Adopt a prone position during lunch breaks to relax the lower back. Supplement calcium and vitamin D in the diet and control weight to reduce the load on the lumbar spine. Use a sit-stand desk in the office for alternating standing and sitting, and add lumbar support when driving. If the pain persists for more than 1 week or is accompanied by lower limb numbness or abnormal urination, timely examination for organic diseases such as lumbar disc herniation and spinal stenosis is necessary.
