Sciatica: What It Is, and What Actually Helps
Key pointers
- Sciatica is pain, tingling or numbness that travels from the low back or buttock down the leg, caused by an irritated nerve root.
- It's a symptom, not a diagnosis. A disc bulge is the most common cause, but not the only one.
- Most cases improve within weeks to a few months with the right plan.
- Movement helps more than rest. Staying active, within tolerance, speeds recovery.
- Physical therapy finds the positions that ease your symptoms and rebuilds strength so the pain doesn't return.
- Get urgent care for leg weakness that is getting worse, numbness in the groin, or bladder or bowel changes.
Sciatica can stop you in your tracks. A burning line from your buttock to your calf. A foot that tingles when you sit. Pain that makes driving, sleeping or picking up your kids hard.
Sciatica is irritation of a nerve root in the low back that sends pain, tingling or numbness down the leg. Effective sciatica treatment focuses on calming the nerve, staying active and rebuilding strength. Most people improve within weeks to a few months without surgery.
Here's what's going on, and what actually helps.
What is sciatica?
The sciatic nerve is the longest nerve in your body. It forms from nerve roots in your lower spine and runs through your buttock and down the back of each leg.
When one of those roots gets compressed or inflamed, you feel symptoms along the nerve's path. That's why sciatica often hurts more in the leg than in the back.
Common symptoms include:
- Pain that travels below the knee
- Burning, electric or shooting sensations
- Tingling or numbness in the leg or foot
- Pain that worsens with sitting, coughing or sneezing
- Symptoms on one side only
What actually helps
1. Keep moving. Bed rest tends to slow recovery. Short, frequent walks are one of the best things you can do early on.
2. Find your relief positions. Some people feel better lying on their stomach. Others prefer lying on their back with knees bent. A physical therapist can test which direction calms your symptoms.
3. Change position often. Long periods of sitting usually aggravate sciatica. Stand up every 20 to 30 minutes.
4. Calm the nerve, then load it. Gentle nerve glides and positional exercises come first. Strength work for the hips, glutes and trunk follows as symptoms settle.
5. Track the trend. Pain moving out of the leg and back toward the spine is a good sign, even if your back feels sore for a while.
What to avoid
- Long stretches of sitting, especially in low, soft chairs or long drives
- Aggressive hamstring stretches that pull on an irritated nerve
- Heavy lifting or high-impact training while symptoms are spreading
- Waiting months for it to "go away" if it isn't improving

When to get urgent care
Go to an emergency room if sciatica comes with:

- New loss of bladder or bowel control
- Weakness in the leg or foot that is getting worse
- Symptoms in both legs at once
These can signal a condition that needs immediate medical attention.
Frequently asked questions
How long does sciatica last?
Many cases improve noticeably within a few weeks, and most settle within a few months. If yours isn't improving after two to three weeks, get it assessed.
Is walking good for sciatica?
Usually, yes. Short, easy walks keep the area moving and often ease symptoms. Stop if walking makes leg pain spread further down.
Should I stretch my hamstrings for sciatica?
Often not at first. Pulling hard on an irritated nerve can make it worse. Gentle nerve glides guided by a PT are a safer start.
Can physical therapy help sciatica?
Yes. PT helps you find relief positions, stay active and build strength so symptoms are less likely to return.
Do I need a referral for sciatica treatment in Massachusetts?
No. Massachusetts allows direct access to physical therapy. Read do you need a referral to see a physical therapist in Massachusetts.
Do I need surgery for sciatica?
Most people don't. Surgery is usually considered for severe or worsening weakness, or when symptoms don't respond to several months of conservative care.
