Lower Back Pain from Sitting in an Office Chair

Lower back pain from sitting in an office chair can be alleviated through adjusting posture, taking regular breaks, applying heat therapy, strengthening the back muscles, and using medication, while also paying attention to lifestyle details to prevent recurrence.

1. Adjusting Posture
   Maintaining the natural curvature of the lumbar spine is crucial. Choose a chair with a backrest, place a soft pillow or use an ergonomic lumbar support at your waist to keep the lumbar support against your lower back; keep your feet flat on the ground with your knees and hips at a 90-degree angle, avoiding prolonged slouching or leaning forward; let your elbows hang naturally and keep them perpendicular to the table at a 90-degree angle. Adjust your posture slightly every 30 minutes to reduce continuous pressure on the lumbar spine from a single position.

2. Taking Regular Breaks
   Sitting continuously for more than an hour can lead to poor blood circulation in the lower back. It is recommended to get up and move for 3-5 minutes every hour. You can perform gentle stretching exercises such as waist rotations and side bends, or engage in low-intensity activities like standing against a wall or walking to promote blood circulation and relieve muscle tension.

3. Applying Heat Therapy
   For chronic strain-related lower back pain, apply a warm towel at around 40°C to the lower back for 15-20 minutes, 2-3 times a day. Heat therapy can dilate blood vessels and accelerate the removal of metabolic waste, with gentle massage enhancing the effect. For acute sprains, cold compresses should be applied within the first 48 hours, followed by heat therapy later. The use of physiotherapy devices should be under medical advice.

4. Strengthening Back Muscles
   Perform core muscle training such as the Superman exercise, glute bridge, and plank every day for 10-15 minutes each session; swimming and the cat-cow pose in yoga can enhance the endurance of the back muscles and improve lumbar stability. Exercise should be progressive to avoid exacerbating injuries with strenuous activities. Patients with osteoporosis need to adjust the intensity.

5. Using Medication
   For significant pain, non-steroidal anti-inflammatory drugs (such as diclofenac sodium sustained-release tablets, celecoxib capsules) or topical flurbiprofen gel patches can be used under medical advice; muscle relaxants like eperisone hydrochloride tablets can be used for muscle spasms; patients with osteoporosis need to combine anti-osteoporosis drugs (such as alendronate sodium tablets). All medications should be used after excluding contraindications.

Suggestions for Preventing Recurrence: 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 your diet with calcium and vitamin D and control your weight to reduce the load on the lumbar spine; equip your office with a sit-stand desk for alternating standing and sitting, and install a lumbar support when driving. If the pain persists for more than a week or is accompanied by lower limb numbness or abnormal urination, timely examination for conditions such as lumbar disc herniation or spinal stenosis is necessary.
