Low back ache is one of the most common musculoskeletal problems I see in practice. In Bangladesh, many people describe it simply as “komorer byatha” and try to live with it for weeks or months before seeking proper evaluation. Some continue office work with long hours of sitting. Some keep lifting at home or at work despite pain. Others take pain medicine on and off without understanding the cause.

Low back ache is not a diagnosis by itself. It is a symptom. The important question is why the pain has started, what structures may be involved, and whether there are any warning signs that need urgent medical attention. Back pain is extremely common, and in many cases it improves with time and proper self-care, but not every episode should be ignored.[1][2]

One important point I want Bangladeshi patients to understand is that low back ache can come from muscles, ligaments, joints, discs, nerves, posture, work habits, arthritis, or sometimes a more serious underlying condition. That is why repeated pain, pain spreading into the leg, or pain affecting walking and sleep deserves a more thoughtful assessment.[1][3]

What low back ache usually means

The lower back supports much of your body weight and is involved in standing, walking, bending, lifting, climbing stairs, and turning in bed. Because this area works constantly, even a relatively small problem can become very uncomfortable.

Common non-serious causes

Many episodes of low back ache are mechanical. This means the pain is related to muscles, ligaments, joints, discs, or movement patterns rather than infection, cancer, or a major neurological emergency.[1][2]

Common causes include:

• muscle strain after lifting, bending, or sudden twisting
• ligament strain
• prolonged sitting with poor posture
• disc-related irritation
• age-related wear and tear in the spine
• weakness and deconditioning
• excess body weight adding strain to the lower back
• physically demanding work

Causes that need more attention

Some patients have back pain because of a disc problem, narrowing around nerves, inflammatory disease, fracture, infection, or another medical condition. Sometimes the pain is not just in the back but also travels to the buttock, thigh, calf, or foot, which can suggest nerve involvement.[1][3]

Symptoms that help me understand the problem

When I evaluate a patient with low back ache, I do not focus only on the word “pain.” I want to know the pattern.

Pain after activity or lifting

Pain that begins after lifting something heavy, long travel, repeated bending, or a full day of physical work often suggests a mechanical or soft-tissue problem.

Morning stiffness or pain after rest

Some patients feel worse after getting up from bed or after sitting for a long time. This may happen with mechanical back pain, disc problems, or age-related spinal changes.

Pain going into the leg

If low back ache spreads to the buttock or down the leg, especially with tingling, burning, or numbness, I begin thinking more carefully about nerve irritation such as Sciatica. That does not always mean surgery is needed, but it should not be dismissed.[3]

Pain with cough, sneeze, or sitting

This pattern can happen when the disc is irritated. In some patients, it overlaps with conditions like Intervertebral Disc Prolapse.

Why low back ache is so common in Dhaka and Bangladesh

Bangladeshi patients often face a combination of medical and practical factors that make recovery slower if the problem is ignored.

Daily-life factors

In Dhaka, I commonly see low back ache in people who:

• sit for long hours in offices or while driving
• spend a long time in traffic every day
• sleep on unsuitable bedding
• lift children, grocery bags, water containers, or household loads repeatedly
• work in factories, shops, construction, or physically demanding jobs
• avoid exercise for long periods

Recovery barriers

Recovery is also affected by practical realities. Some people delay assessment because of work pressure. Some cannot easily attend repeated physiotherapy sessions because of distance, traffic, or family responsibilities. Some are afraid that every back pain means an operation, which is not true. In fact, most low back pain is managed without surgery.[2][3]

When low back ache is an emergency

Most low back ache is not dangerous, but some symptoms are red flags and need urgent medical evaluation.

Seek urgent care if you have:

• severe weakness in one or both legs
• loss of bladder or bowel control
• numbness around the groin or saddle area
• back pain after a significant fall, road traffic injury, or other major trauma
• fever with back pain
• unexplained weight loss with back pain
• severe constant night pain
• known cancer history with new persistent back pain
• rapidly worsening numbness or pain down the leg

These warning signs matter because back pain can occasionally be linked to fracture, infection, spinal cord or nerve compression, inflammatory disease, or other serious conditions.[1][3]

How I assess low back ache

A good evaluation starts with history and examination. Many patients think an MRI is the first step, but that is not always necessary.

Questions I usually ask

• When did the pain start?
• Was there a lifting event, injury, or sudden twist?
• Does the pain stay in the back or go into the leg?
• Is there numbness, tingling, or weakness?
• What makes it worse: sitting, standing, walking, bending, coughing?
• Is sleep affected?
• Are there fever, weight loss, or bladder symptoms?
• Is daily work becoming difficult?
