Herniated disc – why it happens and how to cope with it

Have you experienced a sharp or gnawing pain in your lower back that radiates through your hip and thigh, and sometimes even down to your toes? That feeling can be like an electric shock – disrupting movement, sleep, and your ability to work. One of the most common causes behind this kind of pain is a herniated disc. This means the soft inner part of the disc pushes through its outer layer and presses on a nerve root, causing pain and neurological symptoms.

Why does a herniated disc happen?

A herniated disc doesn’t usually happen from one single moment — it’s the result of a longer process. The main factors are:

  • Heredity. The structure of your connective tissue and spinal discs is largely determined at birth. Studies show that genetics accounts for about half or more of disc wear — more than any single lifestyle factor.
  • Natural aging of the disc. Discs start losing fluid as early as your 30s. It’s worth knowing that these changes are very common even in people with no complaints at all — a worn disc doesn’t automatically mean pain.
  • The nature of the load. It isn’t movement or work itself that wears down a disc, but prolonged one-sided strain — especially forward bending combined with weight and twisting. The same applies to long periods of sitting.
  • Smoking. The spinal disc is the largest tissue in the body without its own blood supply, nourished only by diffusion through the vertebrae. Nicotine narrows these tiny blood vessels, and the disc quite literally starves.
  • Incorrect movement or trauma. A sudden twist, a fall, or lifting something heavy in an awkward position can be what triggers the symptoms. In most cases, though, it isn’t the actual cause — just the final straw for a disc that was already weakened.

 

What are the symptoms of a herniated disc?

  • Sharp, burning, or stabbing pain in the lower back that radiates into the leg.
  • Numbness or tingling in the leg.
  • Muscle weakness (e.g. difficulty rising onto your toes).
  • Pain may intensify when coughing, sneezing, or during small movements.

Leg weakness is a special symptom. Pain is an irritation signal — it can be dreadful, but it leaves no lasting damage. Weakness means the nerve fibers themselves are suffering under the pressure. Mild weakness usually recovers either way (surgery or not), but with moderate or worsening weakness, timing matters: the longer the pressure continues, the higher the risk that some of that strength won’t come back. You can wait out pain for as long as you can tolerate it. Not weakness.

⚠️ If you experience sudden loss of bladder or bowel control, or severe weakness in your legs, see a doctor immediately – this can be a sign of serious nerve damage that needs urgent care.

MRI of a herniated disc, a cause of back pain

 

How is a herniated disc diagnosed?

A doctor or physiotherapist starts with a thorough examination – testing muscle strength, reflexes, and sensation. Definitive confirmation is usually provided by an MRI (magnetic resonance imaging) scan, which shows which disc is affected and how large the herniation is.

Three grades that appear in an MRI report:

  • Protrusion — the outer ring of the disc is intact but bulges outward.
  • Extrusion — the ring has torn and material has come through.
  • Sequestration — a fragment has broken off completely.

Extrusion sounds worse than protrusion, and it is. But here’s a surprising twist: large extrusions and sequestrations tend to resolve on their own the best. The material that has come out is exposed to blood, so the body recognizes it as foreign and starts breaking it down. A small protrusion, still contained within the ring, stays out of the immune system’s reach and often lingers longer.

 

What are the treatment options?

How does the body heal itself? The herniated disc material doesn’t “go back in” — the body clears it away. Scavenger cells (macrophages) move in, new blood vessels form, and the material shrinks and is reabsorbed. On follow-up MRI scans, this material disappears or shrinks significantly in about two-thirds of people.

Timeframe: for most people, things start improving within 6–12 weeks, with full resolution taking 6–12 months. Healing isn’t a straight line — it comes in waves, since it’s an inflammatory process.

The good news is that most people recover without surgery. Effective treatment is usually a combination of several methods:

Physiotherapy

A physiotherapist teaches exercises that:

  • strengthen the deep core muscles,
  • improve posture,
  • reduce pressure on the nerve.

Strength before mobility. The most common mistake is jumping straight into stretching and “opening up” the back — that brings momentary relief, but the spine actually needs more support instead. Focus on the deep core muscles, glutes, and spinal erectors. Aim mobility work at the hips rather than the lower back: stiff hips force the lower back to overwork.

Massage – when does it help, and when doesn’t it?

Massage doesn’t treat the herniation itself, but it can provide meaningful relief from muscle tension and pain when done correctly:

✔ Reducing muscle tension in the surrounding tissue (e.g. back, glute, and thigh muscles).

✔ Improving circulation and supporting recovery.

✔ Easing stress and tension, which often amplify pain.

⚠️ Massage is not recommended during the acute phase, when pain is very severe or there’s numbness/weakness. Deep direct pressure right on the herniation site should also be avoided. The safest approach is to combine massage with physiotherapy and inform your massage therapist about your diagnosis beforehand.

It’s worth knowing separately: if the herniation comes with a spasm in the glute muscle, don’t massage or stretch it with deep pressure during the acute phase. This spasm isn’t a local muscle problem — it’s a result of nerve root irritation, and firm pressure in the area where the sciatic nerve runs through can actually amplify the symptom instead. Heat, gentle movement, and changing position work better than deep tissue work during the acute phase.

Medication

Painkillers and anti-inflammatory medication help with acute pain. Nerve-pain medications are sometimes used as well.

Surgery

Surgery is not the first option, and most people never need to go there. It’s considered when:

  • the pain is severe and doesn’t respond to treatment even after 6–8 weeks,
  • symptoms are worsening,
  • there’s a risk of permanent nerve damage.

Weakness is the exception on this list. Pain is an irritation signal — it can be dreadful, but it leaves no lasting damage, so you can wait it out for as long as you can tolerate it. Weakness means the nerve fibers themselves are suffering under the pressure, and the longer it continues, the higher the risk that some of that strength won’t fully return.

What happens during surgery

The most common procedure is a microdiscectomy. The incision is 2–4 cm, and the muscles aren’t cut through — they’re simply moved aside. The surgeon works under a microscope, carefully shifts the nerve root out of the way, and removes the piece of disc that’s pressing on it.

The disc itself stays in place and keeps working. Nothing is replaced or fused with screws — that’s a common fear, but it doesn’t apply here. The operation takes 45–90 minutes, is often done as day surgery, and patients are usually walking the same day. Many people find their radiating leg pain is gone the moment they wake up.

What the research shows

Large comparative studies have reached a fairly consistent conclusion: surgery gives faster relief, but after a year or two, the pain and function of operated and non-operated people tend to be similar overall. Surgery changes less where you end up than how quickly you get there.

What surgery costs in the long run

Surgery removes a bit of material from the disc, and that leaves a mark: the disc ends up slightly lower and wears faster afterward than it would have otherwise. Two-year studies don’t capture this — they measure pain and function, while wear plays out over decades. If your disc was largely healthy before, surgery can kick-start wear that might not have started so soon otherwise. If the disc was already significantly worn, the added damage is smaller — that process was already under way. This is why surgery isn’t a decision you can base on current pain alone: what your spine looks like in ten or twenty years is also at stake.

How to decide

Surgery buys you faster relief. The price is faster disc wear over the long run. Conservative treatment preserves the disc better, but the path is longer and less certain — no one can guarantee when improvement will come. The risk of recurrence remains on both paths, since a ring that’s once been damaged never quite returns to what it was.

There’s no universally right answer. What tips the scale is the severity of symptoms, whether weakness is present, how long treatment has already been tried, and, quite honestly, how much that in-between period costs a particular person in their own life.

How can you prevent a herniated disc?

The best treatment is always prevention. A few simple but consistent steps can significantly reduce the risk:

  • Movement is medicine. Regular exercise strengthens the deep core muscles that keep the spine stable. Even daily walking or swimming makes a big difference.
  • Learn to lift correctly. When lifting weights, keep your back straight, bend at the knees, and avoid sudden twists while carrying a load.
  • Workplace ergonomics. If you spend a lot of time at a computer, mind your chair height and screen position, and take stretch breaks every hour.
  • Weight management. Excess body weight loads the spine and speeds up disc wear.
  • Giving up bad habits. Smoking reduces blood supply and speeds up disc degeneration.
  • Regular stretching and relaxation. Yoga, pilates, or even simple morning stretches help maintain flexibility and prevent muscle tension.

💡 Think of prevention as everyday “back care” – small, consistent steps mean you won’t have to fight pain later.

 

Can a herniated disc recur in the same spot?

Yes, it can, and the risk is somewhat higher than for someone who has never had a herniation. Once a ring has torn, it never quite returns to what it was — that spot stays weaker and more sensitive to overload.

After surgery, an opening remains in the ring, which heals with scar tissue. Studies show the disc herniates again at the same spot in roughly 5–15% of people. Most recurrences happen within the first three months, while the scar is still fresh — the risk drops afterward, but never disappears completely. That’s exactly why post-surgery restrictions in the first weeks (no bending forward, no twisting under load, no lifting heavy objects) are so strict.

The risk is also higher with smoking, heavy lifting, a sedentary lifestyle, or weak core muscles. The good news is that the right exercises and mindful body use can reduce it significantly — which is exactly why strengthening the deep core muscles and improving everyday movement patterns are so central in rehabilitation.

Summary

A herniated disc doesn’t have to mean a lifetime of back pain. Timely diagnosis, physiotherapy, and a mindful lifestyle help most people recover fully. Massage is a safe and effective complementary therapy when done at the right time and with the right technique – and used this way, it can be a valuable part of recovery.
