When Back Pain Is a Spine Problem — and When It Isn't

Almost everyone gets back pain. Most of it has nothing to do with the spine’s nerves and settles within a few weeks whatever you do. But a small proportion is a disc or nerve problem, and a much smaller proportion needs attention quickly.

Knowing which is which saves people two opposite mistakes: rushing into an MRI and a surgical opinion for pain that would have resolved on its own, and ignoring symptoms that genuinely needed to be seen.

Read this part first: the warning signs

Get medical attention immediately, the same day, if back pain comes with any of these:

• Loss of bladder or bowel control, or numbness around the groin, inner thighs or back passage
• Weakness in a leg or foot that is getting worse — a foot that drags or slaps, difficulty pushing off
• Fever with back pain, particularly with night sweats or recent infection
• Severe pain after a fall or accident, especially if you have osteoporosis
• Unexplained weight loss alongside back pain, or a history of cancer
• Pain that is markedly worse at night and not relieved by lying still

The first of these is called cauda equina syndrome. It is uncommon, but it is one of the few genuine emergencies in spine care — treated within hours the outlook is good, and delay can cause permanent damage. It is worth over-reacting to.

Everything else in this article assumes none of the above applies.

Ordinary back pain versus a nerve problem

The useful question is not how much it hurts. It is where the pain goes and what comes with it.

Mechanical back pain — the common kind — usually:

• Stays in the back, or spreads a little into the buttock
• Changes with position; there is some way of sitting or lying that eases it
• Started after a particular movement, or after a period of unusual load
• Feels stiff, especially first thing in the morning
• Improves noticeably within two to six weeks

Nerve-related pain — a disc or bone pressing on a nerve root — usually:

• Travels below the knee, down the back or side of the leg — this is sciatica
• Comes with pins and needles, numbness, or a burning line in a specific area
• Is worse on coughing, sneezing or straining
• May come with weakness — a foot that catches on steps, difficulty on tiptoes
• Sometimes hurts more in the leg than in the back

That last point matters. A patient whose leg pain has become worse than their back pain has usually developed a nerve problem, even if the back settled.

What is actually going on inside

Disc herniation (“slipped disc”). The soft centre of a disc pushes through its outer ring and presses on a nerve root. Nothing has actually slipped. Most herniations shrink on their own over weeks to months.

Spinal stenosis. The canal carrying the nerves narrows, usually with age. The signature complaint is different from a disc: pain and heaviness in the legs on walking, relieved by sitting or bending forward. People notice they can push a shopping trolley much further than they can walk unaided.

Cervical (neck) problems. The same processes in the neck, producing pain, tingling or weakness in the arm and hand rather than the leg.

Degenerative changes. Wear in discs and facet joints. Present on scans of most people over 40, frequently causing no symptoms at all — which is exactly why scans have to be read alongside the examination, not instead of it.

Why we are careful about early MRIs

Scans of people with no back pain whatsoever commonly show disc bulges and degenerative changes. If someone with three weeks of ordinary back pain has an MRI, we are likely to find something — and then face the temptation to treat a finding that was never the cause.

So the sequence matters. History and examination first. Imaging when the picture calls for it: pain persisting beyond about six weeks, any neurological symptom, or a red flag. At that point the MRI answers a specific question rather than fishing for one.

What treatment usually looks like

For most people, in this order:

1. Stay active. Not bed rest. Walking and normal movement within the limits of pain.
2. Short-term medication for pain and inflammation, so you can keep moving.
3. Physiotherapy, focused on core and postural strength — the durable part of the treatment.
4. Ergonomic changes. Chair height, screen height, how long you sit unbroken, how you lift.
5. Time. Most disc problems improve substantially over six to twelve weeks.

If that does not work, targeted injections can settle a badly inflamed nerve root and are often enough on their own.

Surgery is considered when leg pain has not settled after six to twelve weeks of proper conservative treatment, when there is progressive weakness, or in an emergency such as cauda equina. When it is needed, it is usually a microdiscectomy — removing the fragment pressing on the nerve through a small incision, often as a day-care or one-night procedure.

The large majority of people who consult a neurosurgeon for back pain never have an operation. That is the normal outcome, not a failed consultation.

When to see a neurosurgeon in Uppal

Book an appointment if:

• Back or neck pain has not improved after four to six weeks
• Pain travels below the knee, or into the arm and hand
• You have numbness, tingling or weakness anywhere in a limb
• Walking distance is shrinking because of leg pain or heaviness
• Surgery has been recommended and you want an independent opinion
• You have an MRI report you do not fully understand

Dr. Srinivas Thankari consults at UNO Super Speciality Clinics, Uppal, opposite the Uppal bus stop. Bring your MRI films, not just the report — the films are what a surgeon actually reads — along with previous prescriptions and a short note of when the symptoms started and what makes them better or worse.

And if you have any of the red-flag symptoms listed at the top of this article, do not wait for an appointment. Go to a hospital emergency department now.
