How long does sciatica take to heal?

Most people see meaningful improvement within 4 to 6 weeks, and the majority recover within 3 months without surgery. Recovery is rarely linear. Leg symptoms often improve in stages, and some residual sensations can linger for several months even as function returns. The most useful signal I track is whether pain is centralizing back toward the spine, which tends to predict a faster trajectory.

Can I still work with sciatica?

For most people, yes. Staying active and at work in some capacity is linked to better outcomes. NICE and the Lancet Low Back Pain Series both recommend continued activity rather than bed rest. What usually helps is modifying sitting time, lifting demands, and driving exposure during the acute phase. Complete rest beyond a day or two tends to slow recovery, not speed it up.

Do I need an MRI for sciatica?

Usually not in the first 4 to 6 weeks. NICE NG59 and the American College of Physicians guidance both recommend reserving MRI for cases with red flags, progressive weakness, or symptoms that fail to improve with conservative care where imaging would actually change management. Imaging too early often shows disc changes that are present in pain-free people and can lead to treatment you do not need.

Is walking good for sciatica?

Usually yes, as long as it does not send symptoms further down the leg. Regular, gentle walking helps nerve mobility, reduces stiffness, and keeps you out of prolonged sitting, which is one of the biggest aggravators I see. If walking centralizes or eases leg pain, that is a positive sign. If it reliably worsens leg symptoms, I adjust distance, pace, or posture.

What positions make sciatica worse?

Prolonged sitting, slumped driving posture, and deep forward bending are the most common aggravators. All three increase load on the lumbar discs and narrow the space where the nerve root exits. Coughing, sneezing, and bearing down can spike symptoms too. Many patients feel better standing, walking short distances, or lying with the knees supported.

When should I worry about sciatica?

Seek urgent medical care for loss of bladder or bowel control, numbness in the saddle area, rapidly progressing leg weakness, or foot drop. These can signal cauda equina syndrome or significant nerve compromise. Severe, unrelenting night pain, unexplained weight loss, or fever with back pain also warrant medical review rather than physiotherapy as a first step.

Does sciatica always come from a disc?

No. A herniated disc is the most common cause, but sciatic-type pain can also come from foraminal stenosis, deep gluteal or piriformis involvement, sacroiliac joint irritation, or referred pain from the hip. Sorting out which structure is actually driving symptoms matters, because the plan changes significantly depending on the source.

Do I need surgery for sciatica?

Surgery is rarely the first step. The SPORT trial (Weinstein et al., JAMA 2006) and subsequent Cochrane reviews show that at 1 to 2 years, outcomes for disc-related sciatica converge between surgery and structured conservative care, though surgery can offer faster early relief. Surgery is typically considered when there is progressive neurological loss, or when symptoms remain severe and disabling after 6 to 12 weeks of appropriate treatment.

Inside Overview

The Science of Sciatica

Link copied

Sciatica describes pain along the sciatic nerve path, usually from compression or irritation at the spine level. The nerve can be affected by disc material, bone spurs, or tight muscles along its path. Similar to general low back pain, sciatica often involves disc dysfunction, but with the added complexity of nerve root compression or irritation. When the nerve is irritated, it can cause pain, numbness, or weakness anywhere along its path from the back to the foot. The location and type of symptoms help identify where the problem originates. In some cases, sciatica may occur alongside degenerative disc disease or spinal stenosis, requiring careful assessment to address all contributing factors. Sciatica rehabilitation centres on identifying the specific source of nerve irritation and applying targeted strategies to reduce compression. Sciatic nerve pain relief is typically achieved through a combination of directional exercises, neural mobilization, and activity modification tailored to the individual presentation.
