What Not to Do With Sciatica: Mistakes to Avoid

Most sciatica improves on its own within a few weeks, but certain habits, movements, and well-meaning remedies can slow your recovery or make the pain worse. Roughly three out of four people see their symptoms resolve without surgery, according to Harvard Health Publishing. What you avoid during that healing window matters just as much as what you do.

Don’t Stay in Bed Too Long

When sciatica flares up, lying down feels like the obvious move. But extended bed rest doesn’t actually speed recovery. A Cochrane review comparing bed rest to staying active found no significant difference in pain relief for sciatica patients at any time point. There was, however, a borderline advantage in physical function for people who stayed active versus those who rested in bed, measured at three to four weeks out. The takeaway: bed rest is not a helpful strategy for sciatica, and it may slightly delay your ability to get back to normal movement.

That doesn’t mean you should push through severe pain. Short rest periods are fine. But lying in bed for days at a time allows your muscles to weaken and stiffen, which can make the underlying problem harder to resolve. Gentle walking, even for short periods, is a better default than staying horizontal.

Exercises That Make It Worse

Exercise is generally good for sciatica recovery, but certain movements put direct stress on the sciatic nerve or the discs pressing against it. Avoid these while you’re symptomatic:

  • Heavy deadlifts and bent-over rows. Straight-leg deadlifts stretch the hamstrings and lower back simultaneously, loading the exact pathway of the sciatic nerve. Bent-over rows create similar stress, especially if your back rounds during the lift.
  • Deep squats. Full-depth squats compress the lower spine under load, which can aggravate a bulging or herniated disc.
  • High-impact activities. Running, jumping, and plyometrics send repeated shock through the spine. Each landing compresses the discs and can irritate an already inflamed nerve root.
  • Twisting movements. Rotational exercises, like Russian twists or golf swings, can shift disc material further into the nerve. Avoid combining bending and twisting under any kind of load.

Low-impact activities like walking, swimming, or gentle stretching that doesn’t involve deep forward folds tend to be safer. The goal is to stay moving without repeatedly compressing or stretching the irritated nerve.

Sitting Mistakes That Add Pressure

Sitting for long periods is one of the most common ways people unknowingly worsen sciatica, especially with poor posture. A slumped position fails to support your lower back and can increase the curvature of your spine over time, a condition called kyphosis. That added curvature pushes more pressure onto the discs in your lumbar region, right where the sciatic nerve originates.

Crossing your legs is another quiet aggravator. A 2015 study found that sitting cross-legged for extended periods elongates the piriformis muscle, which runs from the lower spine to the top of the thigh, directly over the sciatic nerve. This position also rotates the pelvis and creates left-right asymmetry in the lumbar spine. In the short term it may reduce muscle fatigue, but it increases pressure on the gluteal muscles and can contribute to pelvic misalignment.

If you work at a desk, use a chair with lumbar support and keep both feet flat on the floor. Get up and move for a few minutes every 30 to 45 minutes. Soft, deep couches that let your hips sink below your knees are particularly bad because they force your lower spine into a rounded position.

Lifting the Wrong Way

Improper lifting is one of the most direct triggers for sciatica flare-ups. Bending at the waist to pick something up, rather than squatting down with your knees, puts enormous pressure on your lumbar discs. If you twist your torso while lifting, the risk goes up further because rotational force can push disc material into the nerve root.

Keep objects close to your body when you carry them. Avoid lifting anything heavy during an active flare-up. When you do lift, bend your knees, keep your back straight, and let your legs do the work. This applies to everything from moving boxes to picking up a child off the floor.

Sleeping Positions That Aggravate Pain

Sleeping on your stomach is the worst position for sciatica. It forces your spine to curve toward the mattress, stressing the muscles and joints in your lower back. On a soft mattress, this effect is even more pronounced.

Better options include sleeping on your back with a pillow under your knees, which relaxes the hip flexors and helps maintain the natural curve of your spine. You can also try lying on your side with a thin pillow between your knees to keep your pelvis neutral. If you sleep on your side, keep your injured side on top so it isn’t compressed against the mattress. A small rolled towel or thin pillow under your waist can fill any gap and prevent side bending. The fetal position, with your knees drawn up toward your chest, also opens space between the vertebrae and can relieve nerve pressure.

Using Heat Too Early

Reaching for a heating pad is a common instinct when sciatica strikes, but heat applied during the first 48 hours of an acute flare-up can increase inflammation and make things worse. During this early window, cold therapy is the better choice. Ice numbs the affected area, reduces swelling, and limits the inflammatory response around the nerve. Apply a cold pack wrapped in a cloth for 15 to 20 minutes at a time.

After the first two days, you can switch to heat or alternate between the two. Heat relaxes tight muscles and improves blood flow to the area, which supports healing once the initial inflammation has calmed down. Getting this order wrong is a small mistake that can make a noticeable difference in the first week of a flare-up.

Wearing the Wrong Shoes

High heels shift your weight onto the front of your foot and push your hips forward. Walking or standing in this position for extended periods stretches the hamstrings, and since the sciatic nerve runs right alongside them, that constant tension can irritate an already sensitive nerve. Flat, unsupportive shoes create problems too. Without adequate cushioning, each step transmits more impact up through your legs and into your spine.

During a flare-up, stick with supportive, cushioned shoes that keep your pelvis in a neutral position. Save the heels for after recovery, if at all.

Smoking Slows Disc Healing

Most people don’t connect smoking with back pain, but nicotine directly impairs the health of your spinal discs. Smoking promotes oxidative stress and increases inflammation within the discs while simultaneously reducing the body’s natural anti-inflammatory protections. This creates a cycle where damaged discs heal more slowly and degenerate faster. If a herniated disc is causing your sciatica, smoking is actively working against your recovery.

Red Flags You Shouldn’t Ignore

Most sciatica is painful but not dangerous. There is, however, a rare complication called cauda equina syndrome where the bundle of nerves at the base of your spinal cord becomes severely compressed. This is a surgical emergency. The warning signs include sudden difficulty peeing or pooping (or inability to control either), numbness in your inner thighs, buttocks, or the area around your groin, and rapidly worsening leg weakness. If you develop any combination of these symptoms alongside your sciatica, go to an emergency room immediately. Delay can result in permanent nerve damage.
