Sciatica isn't a diagnosis in itself — it's a symptom of an irritated or compressed sciatic nerve, the longest nerve in your body, running from your lower back through your buttock and down each leg. The most common cause is a herniated or slipped disc in the lower spine pressing on a nerve root. The good news: the vast majority of sciatica settles down on its own with the right conservative care, and surgery is rarely the first step.
Understanding sciatic nerve compression
Sciatica happens when the sciatic nerve — which runs from your lower back, through your buttock, and down the back of each leg — becomes irritated or compressed at its root in the spine. The pain you feel in your leg is actually coming from a problem in your lower back. Several conditions can cause this compression:
How sciatic nerve pain typically presents
Seek emergency care immediately if you experience loss of bladder or bowel control, numbness in the groin or inner thighs (saddle numbness), or progressive weakness in one or both legs. These can be signs of cauda equina syndrome, a rare but serious emergency that requires urgent evaluation and often urgent surgery to prevent permanent nerve damage.
Clinical exam first, imaging when needed
In most cases, sciatica can be diagnosed through a careful history and physical examination, without needing any scans at all.
Most cases heal without surgery
The great majority of sciatica cases — well over 90% — resolve on their own within 6 to 12 weeks with the right conservative approach. Treatment is stepped, starting with the simplest, least invasive options.
Key takeaway: Surgery is not the default treatment for sciatica. For most patients, the right conservative plan — not strict rest, but guided activity and physiotherapy — resolves the pain within weeks.
Movement helps recovery
Gentle, guided movement is one of the most effective tools in sciatica recovery — it keeps the spine mobile, eases pressure on the nerve, and prevents the stiffness and deconditioning that prolonged rest can cause. A structured, progressive routine works far better than either staying still or pushing through sharp pain.

A clinician's perspective on sciatica
One of the most common misconceptions I see in my clinic is that sciatica automatically means surgery is coming. In reality, the nerve pain that brings most patients to me — however sharp and frightening it feels — settles down with time and the right conservative approach in the overwhelming majority of cases. My job in those first weeks isn't to rush toward an operating table; it's to get the diagnosis right, rule out the rare emergencies that do need urgent attention, and guide activity and physiotherapy so the nerve has the best chance to heal on its own. Surgery has its place, and when it's genuinely needed — significant weakness, or pain that simply isn't responding after a fair trial of conservative care — I don't hesitate to recommend it. But it should never be the first conversation we have.
