Low back pain that worsens upon sitting is generally caused due to pressure build up over the lumbar discs while sitting for prolonged periods of time. A normal spine has a S bend. Inappropriate posture while sitting can gradually cause change in the normal S bend curvature to abnormal C bend curvature. This increases the intra-disc pressure causing pain over the lumbar region. This over a period of time can flatten the lumber disc leading to pinching of the nerves passing through that area.
What Causes Low Back Pain When Sitting Down?
Low back pain is most commonly caused by mechanical reasons. These include:
- Muscle Strain as a Cause for Low Back Pain When Sitting Down: Muscle strain usually occurs after certain abnormal movement such as twisting, lifting heavy objects etc. or after a sudden jerk in traumatic events such as motor vehicles accidents, falls etc.

- Low Back Pain When Sitting Down Caused Due to Disc Herniation: It is a condition where the intervertebral disc bulges into the space containing the spinal cord causing low back pain. The pain is more when sitting down as the disc space gets reduced further.
- Arthritic Changes: Degenerative changes over the vertebrae leads to low back pain when sitting down or with any activity.
- Spinal Stenosis: Pain and discomfort caused over the low back in view of narrowing of the bony canal causing build-up of pressure over the nerves.
Other Causes of Low Back Pain Include:
- Functional causes
- Systemic infection
- Inflammatory conditions such as rheumatological issues
- Vertebral fracture

- Weight Loss: Risks of developing low back pain increases with weight gain. Thus, it is advised to maintain weight within acceptable limits.
- Lifting Action: It is advised to bend at knees rather than at the waist while lifting heavy objects to prevent back pain.
- Appropriate Clothing: One should avoid tight fitting clothing that may restrict sitting, bending and movement in general. Wearing high heels on a regular basis also increases risk of developing back pain.

Low back pain is a very common condition that affects every individual at least once in their lifetime. Pain over the lumber region is generally caused due to inappropriate posture while sitting and other activities. This causes change in the normal curvature of the spine, causing increased pressure over the intervertebral discs. The increased pressure over a period of time can cause nerve compression leading to pain and discomfort. The pain generally dissipates with simple home treatment; however, in advanced cases, specialized attention may be required. Pain medications and muscle relaxants are recommended for management of pain and inflammation. Physical manipulation by a physical therapist is also beneficial. It is advised to maintain appropriate posture to avoid the risk of causing back strain and low back pain when sitting down.
