Sciatica is a type of nerve pain that starts when the sciatic nerve becomes irritated or squeezed. The sciatic nerve is the largest nerve in your body. It runs from your lower back through your hips and buttocks and down each leg.
Sciatica often feels like a sharp, burning, or shooting pain that travels from your lower back into your buttock and down one leg. Some people also have numbness, tingling, or weakness in the affected leg or foot. The pain can be mild for some people, but for others it can make standing, walking, or sitting uncomfortable.
Not every case of sciatica can be prevented. However, healthy daily habits can help lower your risk and keep your back strong. Here are some simple ways to help protect your spine and reduce your chances of developing sciatica.
Stay Active
Regular movement helps keep your muscles strong and flexible. Strong muscles support your spine and take pressure off your back. Try activities like:
- Walking
- Swimming
- Riding a bike
- Gentle stretching
Aim for about 30 minutes of activity most days of the week. If you are just getting started, begin with short walks and slowly build up your time.
Lift the Right Way
Lifting heavy objects the wrong way can strain your back. When you lift:
- Bend your knees, not your waist.
- Keep the object close to your body.
- Lift with your legs.
- Avoid twisting while you carry something.
If an object feels too heavy, ask for help.
Watch Your Posture
Good posture helps reduce stress on your spine. When sitting:
- Keep both feet flat on the floor.
- Sit with your back supported.
- Keep your shoulders relaxed.
- Try not to slouch.
If you work at a desk, stand up and stretch every 30 to 60 minutes. Even a short walk around the room can help.
Additional Tips
- Keep Your Core Strong – Your core muscles include your stomach, back, and hips. These muscles help support your spine. Simple exercises, such as bridges, pelvic tilts, or gentle abdominal exercises, can help build strength. Talk with your healthcare provider or physical therapist before starting a new exercise program, especially if you already have back pain.
- Maintain a Healthy Weight – Extra body weight can put more pressure on your lower back. Eating a balanced diet and staying active can help you reach or maintain a healthy weight. Even small changes can make a difference over time.
- Avoid Nicotine– Smoking and other nicotine products reduce blood flow to tissue, including the ones around your spine. Over time, this may increase the risk of back problems.
- Listen to Your Body – Do not ignore ongoing back pain. Rest for a short time if needed, but try not to stay in bed for long periods. Gentle movement is often better than complete rest. If pain gets worse, spreads down your leg, or keeps coming back, it is a good idea to see an orthopedic specialist.
When Should You See a Doctor?
Seek medical care if you have:
- Pain that lasts more than a few weeks
- Pain that gets worse instead of better
- Numbness or weakness in your leg or foot
- Trouble walking because of the pain
Go to the emergency room right away if you suddenly lose control of your bladder or bowels, or if you have severe weakness in one or both legs. These symptoms are rare but need immediate medical care.
Key Takeaways
You cannot always prevent sciatica, but healthy daily habits can lower your risk. Staying active, using good posture, lifting safely, and keeping your muscles strong all help protect your back.
If you develop pain that travels from your lower back into your leg, don’t ignore it. Early treatment may help relieve symptoms and get you back to the activities you enjoy.
