Sit in a chair with good lumbar support and proper position and height for the task. Keep shoulders back. Switch sitting positions often and periodically walk around the office or gently stretch muscles to relieve tension. A pillow or rolled-up towel placed behind the small of the back can provide some lumbar support. During prolonged periods of sitting, elevate feet on a low stool or a stack of books.
Increasing general physical activity has been recommended, but no clear relationship to pain or disability has been found when used for the treatment of an acute episode of pain.[48][54] For acute pain, low- to moderate-quality evidence supports walking.[55] Treatment according to McKenzie method is somewhat effective for recurrent acute low back pain, but its benefit in the short term does not appear significant.[1] There is tentative evidence to support the use of heat therapy for acute and sub-chronic low back pain[56] but little evidence for the use of either heat or cold therapy in chronic pain.[57] Weak evidence suggests that back belts might decrease the number of missed workdays, but there is nothing to suggest that they will help with the pain.[50] Ultrasound and shock wave therapies do not appear effective and therefore are not recommended.[58][59] Lumbar traction lacks effectiveness as an intervention for radicular low back pain.[60]
If low back pain gets worse or does not improve after two to three days of home treatment, contact a primary-care physician. The physician can evaluate the patient and perform a neurological exam in the office to determine which nerve root is being irritated, as well as rule out other serious medical conditions. If there are clear signs that the nerve root is being compressed, a physician can prescribe medications to relieve the pain, swelling and irritation; he or she also may recommend limitation of activities. If these treatment options do not provide relief within two weeks, it may be time to consider other diagnostic studies and possibly surgery.
