That sharp, shooting pain down the back of one leg can stop you in your tracks. Maybe it flares when you stand up, lingers when you sit, and makes you wonder if you've done something serious to your back. The good news: sciatica is common, and for most people it settles down on its own.
What is sciatica, and why does it happen?
To relieve sciatica, it helps to know what's actually going on. Sciatica is pain that travels along the path of the sciatic nerve, running from your lower back through your hip and buttock and down your leg. It usually affects only one side. The sciatic nerve is the body's largest nerve, formed from nerve roots in your lower spine (L4 to S3), and it can be up to about 2 cm in diameter.
The pain comes from pressure or irritation on that nerve where it exits the spine. The most common cause is a herniated (slipped) disk pressing on a nerve root. Bone spurs and a narrowing of the spinal canal, called spinal stenosis, can do the same thing. Knowing the cause matters less than you'd think for early treatment, because the first steps to relieve sciatica are the same for most people.
How to relieve sciatica at home
For most people, sciatica improves with simple self-care you can start right away. The single most important thing is to keep moving. It can feel counterintuitive when you're hurting, but staying active relieves sciatic pain better than bed rest, and too much rest can actually make symptoms worse.
Alongside staying active, a few measures can take the edge off:
- Stay active: continue your normal daily activities as much as the pain allows, rather than lying down for long stretches.
- Use cold, then heat: apply a cold pack to your lower back for the first few days, then switch to a hot pack or heating pad.
- Try gentle stretches: slow knee-to-chest and gluteal (buttock) stretches can ease tension along the nerve.
- Consider OTC pain relief: over-the-counter anti-inflammatories such as ibuprofen may help. Follow the label and check with a pharmacist or clinician if you take other medications or have health conditions.
How long does sciatica last?
This is the question on most people's minds, and the answer is reassuring. Most cases of sciatica resolve within about four to six weeks with conservative self-care alone, even without specific medical treatment. Many people start feeling better well before that.
The wider picture is encouraging too. About 90% of people with sciatica are treated successfully without surgery. If you're staying active and your pain is gradually trending in the right direction, that's usually a sign things are on track.
Stretches and exercise that help
Movement is medicine for sciatica. Gentle stretching keeps the nerve and surrounding muscles from stiffening up, and structured exercise builds the strength to support your lower back over time.
A common, evidence-based approach is to start with gentle daily stretches, then add strengthening once the sharpest pain eases. Low-impact activity such as walking or water-based exercise is a good way to stay mobile without straining your back. National guidelines recommend a group exercise program as a first-line treatment, and physical therapy is often highly effective. Notably, guidelines advise against treatments like spinal traction, acupuncture, TENS, and ultrasound for sciatica, so it's worth focusing your energy on movement instead.
When to see a doctor for sciatica
Most sciatica gets better on its own, but some situations call for professional care. As a general rule, check in with a healthcare professional if your pain does not improve after about six weeks, keeps getting worse, or is severe enough to disrupt your daily life. A clinician can confirm the diagnosis and discuss next steps, which may include physical therapy, prescription medications, or a steroid injection for acute, severe pain.
Some symptoms are red flags that need urgent attention. Seek emergency care right away if you develop progressive weakness in a leg, or any loss of bladder or bowel control. These can signal a rare but serious condition affecting the nerves at the base of the spine and should never be ignored. Surgery is generally reserved for cases with severe weakness, bowel or bladder problems, or pain that worsens despite other treatments.
