Slipped Disk
What a slipped disc is
Between the bones of the spine (the vertebrae) sit discs that act as cushions. Each disc has a tough outer ring and a soft, jelly-like centre. A herniated disc — commonly called a slipped disc, although nothing actually slips — happens when part of the soft centre pushes out through a weak spot in the outer ring.
The bulging material can press on or irritate a nearby nerve root. That is why a disc problem in the lower back often causes pain down the leg, and one in the neck causes pain down the arm. Disc herniations are most common in the lower back, followed by the neck.
Many people have disc bulges on a scan without any symptoms at all. A disc becomes a problem when it irritates a nerve. The encouraging fact is that most people improve within weeks to a few months without surgery, as the inflammation settles and the body gradually shrinks the herniated material.
Symptoms
Symptoms depend on where the disc is and which nerve it affects:
- Back pain or neck pain, sometimes starting after lifting, bending or twisting, and sometimes with no clear cause
- Sciatica — sharp, burning or electric pain running from the buttock down the back or side of the leg, often below the knee
- Arm pain spreading from the neck to the shoulder, arm or hand, when the disc is in the neck
- Numbness or tingling in part of the leg, foot, arm or hand
- Muscle weakness, such as difficulty standing on the toes or heels, or a weak grip
- Pain that is worse when sitting, bending forward, coughing or sneezing
Leg or arm pain is often worse than the back or neck pain itself. That pattern is a useful clue that a nerve is involved.
Causes and who is at risk
With age, discs lose water and become less flexible, so the outer ring can tear more easily. A single awkward movement often triggers symptoms in a disc that was already weakened. You are more likely to have a slipped disc if you:
- Are between your thirties and fifties
- Do work that involves heavy lifting, repeated bending or twisting, or long hours of driving
- Sit for long periods with little movement
- Carry extra body weight
- Smoke, which reduces the blood supply that keeps discs healthy
- Have a family history of disc problems
How it is diagnosed
The doctor will ask about your pain and do a neurological examination, testing strength, sensation and reflexes in your arms or legs to see which nerve is affected. The straight leg raise test, in which the doctor lifts your straightened leg while you lie on your back, often reproduces sciatica when a lower back disc is pressing on a nerve.
An MRI is the scan that shows discs and nerves clearly. It is not needed for everyone at the start, because most people get better without it and the findings rarely change early treatment. It is advised when there are warning signs, when weakness is getting worse, when pain has not improved after several weeks of treatment, or when surgery or an injection is being considered. An X-ray does not show discs, though it may be used to look at the bones. Nerve conduction studies are sometimes used when the diagnosis is unclear.
Which doctor to see
A general physician can assess new back or neck pain and start treatment. For pain that is not settling, or for leg or arm symptoms, an orthopaedic surgeon — particularly one who focuses on the spine — or a neurosurgeon is the right next step. Both operate on the spine, and both advise against surgery when it is not needed.
A rehabilitation physician specialises in non-surgical treatment and recovery. Physiotherapists are allied-health professionals who guide the exercises that most people need. You can find orthopaedic surgeons in Bengaluru, neurosurgeons, rehabilitation physicians and physiotherapists on The Doctor Index.
Treatment
Most people recover with non-surgical treatment. The aim is to control pain well enough that you can keep moving while the disc settles.
Staying active
Staying active helps recovery more than bed rest. A day or two of reduced activity during severe pain is fine, but long periods lying down make stiffness and weakness worse. Short, frequent walks are usually a good start. Avoid heavy lifting and long spells of sitting while the pain is bad.
Medicines
Pain relievers such as paracetamol or anti-inflammatory medicines may be used for a short period. For nerve pain, your doctor may prescribe medicines that act on the nerves; these can cause drowsiness. Avoid buying strong painkillers or muscle relaxants from a chemist without a prescription.
Physiotherapy
Physiotherapy teaches exercises to restore movement, strengthen the muscles that support the spine and gradually return you to normal activity. Traction and passive treatments on their own have less evidence than an active exercise programme.
Injections and surgery
An epidural steroid injection places anti-inflammatory medicine near the irritated nerve. It may ease leg or arm pain for a time and help you engage with physiotherapy, but it does not fix the disc. Surgery, most often a discectomy to remove the portion of disc pressing on the nerve, is considered when there is significant or worsening weakness, when leg or arm pain remains severe despite several weeks of good non-surgical care, or urgently when warning signs appear. Your surgeon will decide based on your examination and scan.
Living with it and preventing it coming back
Once the pain settles, keep up the exercises. Regular walking, core strengthening, a healthy weight and not smoking all help. Lift by bending your knees and keeping the load close to your body, and break up long periods of sitting or driving. Some people have more than one episode; the same principles apply each time. See your doctor again if pain returns with new numbness or weakness.
When it is an emergency
Call 112 or 108, or go to the nearest emergency department straight away, if back pain or sciatica comes with any of these:
- Numbness in the groin, genitals, inner thighs or around the back passage — the area that would touch a saddle
- New difficulty passing urine, being unable to pass urine, or loss of control of the bladder or bowels
- Weakness in both legs, or weakness that is quickly getting worse
- Back pain with fever, unexplained weight loss, a history of cancer, or after a fall or accident
The first two can be signs of cauda equina syndrome, in which the nerves at the bottom of the spine are squeezed. It needs an MRI and often surgery within hours to protect bladder, bowel and leg function.
Questions to ask at your appointment
- Is a disc the likely cause of my pain, and which nerve is affected?
- Do I need an MRI now, or only if things do not improve?
- Which activities are safe, and which should I avoid for now?
- How long should I give non-surgical treatment before reconsidering?
- Would an injection or surgery help me, and what are the risks?
- Which symptoms mean I should come back urgently?
Common questions
Questions people ask
- Is a slipped disc the same as a herniated disc?
- Yes. Slipped disc is the everyday name for a herniated or prolapsed disc. The disc does not actually move out of place; part of its soft centre pushes out through the outer layer and can press on a nerve. A bulging disc is a milder change that often causes no symptoms.
- Will a slipped disc heal without surgery?
- Most do. Symptoms usually improve over weeks to a few months with activity, pain relief and physiotherapy, and scans often show the herniated part shrinking over time. Surgery is kept for people with severe or worsening weakness, warning signs, or pain that does not settle.
- Should I take complete bed rest?
- No. Long bed rest slows recovery and leads to stiffness and muscle weakness. Rest briefly if the pain is severe, then gradually return to walking and normal activities as pain allows, ideally with guidance from a physiotherapist.
- My MRI shows several disc bulges. Do I need an operation?
- Not necessarily. Disc bulges are very common on scans, including in people with no pain. Doctors treat the person, not the scan, and decide on surgery based on your symptoms and examination as well as the MRI findings.
This condition is usually assessed by an orthopaedic surgeon. Every profile shows the doctor’s registration and what has been checked.
