Slipped Disc Treatment
Management of herniated discs, including surgery for selected cases with persistent or significant nerve symptoms
What is slipped disc treatment?
Each disc is a tough fibrous ring around a soft central core. The ring takes the load and the core distributes it. With age the core dries out and the ring develops fissures, and under load a fragment of the core can push through the ring and sit in the canal.
The fragment causes trouble in two ways. It presses the nerve root mechanically, and it releases inflammatory chemicals that irritate the root chemically. The second part explains why a small fragment can be intensely painful and why the pain often settles long before the fragment disappears.
Most fragments shrink. The body treats the extruded material as foreign and gradually absorbs it, and larger extrusions shrink more reliably than small contained bulges. That natural history is the reason the first six weeks are given to letting things settle, and it is why the majority never need an operation.

How it is diagnosed
The examination is aimed at establishing which nerve root is involved and how much it is being affected. Your doctor tests the power of specific muscle groups in the leg and foot, checks the reflexes at the knee and ankle, and maps the area of altered sensation, since each root has its own territory.
Raising the straight leg reproduces the pain when a root is under tension and helps confirm the level. They also ask about bladder and bowel control and sensation around the perineum, because loss of these is an emergency and changes everything about the timing.
An MRI is the imaging that shows discs and nerve roots, and it is requested when the pain has not settled in six weeks, when there is muscle weakness, or when a plan for intervention is being made. Its findings are only meaningful when they match the examination, since bulges are visible in the scans of a great many people who have no trouble at all.
Recovery
Without surgery, the pattern is a gradual reduction in the distance the pain travels down the leg over weeks, retreating up towards the buttock before it goes. Staying gently active is more effective than bed rest, which weakens the supporting muscles quickly.
After surgery the leg pain is usually gone when you wake up, and it is the back that is sore for the first fortnight. Walking starts the same day or the next. Sitting for long periods, bending and lifting are restricted for around six weeks while the ring of the disc seals.
Desk work returns at two to four weeks, manual work at six to twelve. Numbness in a patch of the leg or foot recovers slowly and sometimes incompletely, since nerve fibres regrow slowly, and a weak muscle regains power over several months.
If it is left untreated
Around three-quarters of people improve substantially within six to twelve weeks with medication, physiotherapy and time, and the fragment shrinks on scans done a year later. Waiting through that period is the standard approach and not a compromise.
Two things override it. Progressive weakness in the leg means the nerve fibres are being damaged, and a muscle that stays weak for months may not fully recover. And loss of bladder or bowel control, or numbness in the saddle area, indicates the whole bundle of nerves at the base of the canal is being compressed, which requires surgery within hours to avoid permanent damage. Anyone with those features should be seen immediately.
Questions about slipped disc treatment
Will the disc go back into place?
It does not slide back, but it does shrink. The body treats the extruded fragment as foreign material and gradually absorbs it, and follow-up scans a year later commonly show a large fragment substantially reduced or gone. The larger the extrusion, the more reliably this happens. That process, along with the settling of the chemical irritation around the nerve, is why most people improve without an operation.
What symptoms mean I should be seen urgently?
Difficulty passing urine or a loss of the sensation that you need to, loss of bowel control, or numbness in the area that would contact a saddle. Together these suggest the whole bundle of nerves at the base of the canal is compressed, and it needs surgery within hours to avoid permanent damage to bladder, bowel and sexual function. Rapidly increasing weakness in a leg or foot also needs same-day assessment.
Is endoscopic removal better than a microdiscectomy?
They relieve the leg pain equally well for the right fragment. The endoscopic route uses a smaller portal and less muscle disturbance, so people are often up and home faster, and it suits a single contained fragment to the side of the canal. A microdiscectomy gives a wider view and better access to a fragment that has broken free and migrated, or to one sitting centrally, and the anatomy on your MRI is what decides between them.
