“Pinched nerve” is the lay term for what clinicians call radicular pain, pain generated by an irritated or compressed nerve root, where it leaves the spine. People describe it vividly: an electric line running down the back of the leg, a burn into the shoulder blade and arm, fingers that tingle in a specific pattern, a leg that feels heavy or unreliable. The distribution is the diagnosis’s calling card, nerve pain travels along the nerve’s map, which is why it can hurt in the calf when the problem is in the lower back.
What “pinches” a nerve
Usually a disc herniation pressing near the root (covered in the disc article), sometimes the bony narrowing of spinal stenosis in older adults, occasionally thickened joints or, in the neck, arthritis narrowing the exit tunnel. Worth understanding: the nerve is often more irritated than mechanically crushed. Inflammation around the root makes it exquisitely sensitive to stretch and pressure, which is why symptoms can be severe with modest findings on a scan, and why they often settle as the inflammation does, even before anything structural changes.
The typical course
For the common disc-related cases, the trajectory is genuinely encouraging: reviews in the New England Journal of Medicine report that sciatica, the leg version, resolves within roughly three months in the large majority of people, with conservative care. Neck versions (cervical radiculopathy) follow a similar pattern for most. “Resolves” does not mean painless by Friday. It means a trend: the pain retreats from the foot upward, the worst spikes space out, sleep returns, and function comes back in steps.
How physiotherapy helps
- Assessment first: mapping the symptoms to a nerve level, testing strength, reflexes, and sensation, and screening for the red flags that change management
- Positions and movements that calm the nerve: directional exercises, many leg cases settle with extension-based movement; neck cases often with specific retraction and posture work, per the neck pain clinical practice guidelines
- Nerve mobility work: gentle techniques that restore the nerve’s ability to glide in its tunnel, introduced when irritability allows
- Gradual reloading: rebuilding strength in the weakened muscles and the spine’s overall capacity as symptoms centralise and settle
- Honest monitoring: weakness that is progressing rather than stable is a referral-back finding, and we will tell you so
When it is not a wait-and-see
Loss of bladder or bowel control, saddle numbness, weakness appearing in both legs, emergency care, immediately. Progressive weakness in one limb (a foot drop developing, a grip failing), or pain that remains severe and disabling after six to eight weeks of proper conservative care, warrants surgical opinion. Those pathways matter; they are also the minority.
