Does sleeping with a pillow between your legs help sciatica?

Sciatica, a term many people have become all too familiar with, refers to the pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg. The discomfort can range from a mild ache to a sharp, burning sensation or excruciating pain.

Different treatments and remedies are recommended to alleviate the pain, one of which is the practice of sleeping with a pillow between your legs. But does this simple adjustment truly offer relief? Let’s delve into the ins and outs of this recommendation.

Guide: How Sleeping with a Pillow Between Your Legs Can Help Sciatica

  1. Understanding Sciatica: Before diving into the remedy, it’s essential to understand the root cause. Sciatica often occurs when a herniated disk, bone spur on the spine, or the narrowing of the spine (spinal stenosis) compresses part of the nerve. This compression causes inflammation, pain, and often some numbness in the affected leg.
  2. Postural Alignment: The spine’s natural curve is maintained when the pelvis is in a neutral position. For those who sleep on their side, the top leg usually drops forward, pulling the spine out of its natural alignment. This can exacerbate sciatic pain. A pillow between the legs helps keep the top leg level with the hip, reducing the torsion on the lumbar spine and, therefore, reducing pressure on the sciatic nerve.
  3. Reduced Muscle Tension: Placing a pillow between your legs can also reduce muscle tension, as it supports the natural alignment of the hips. This, in turn, helps alleviate additional stress or pressure on the sciatic nerve.
  4. Enhanced Circulation: Proper alignment can also improve blood flow. Better circulation might aid in reducing inflammation and pain.
  5. Choosing the Right Pillow: Not all pillows will be effective. For optimal support, the pillow should mold to the shape of your legs and provide adequate support. Memory foam knee pillows, for example, are often recommended as they tend to maintain their shape.
  6. Alternate Positions: While side sleeping with a pillow between the legs is most commonly recommended for sciatica sufferers, back sleepers can also benefit. When lying on your back, placing a pillow beneath your knees can help maintain the natural curve of your spine.
  7. Consultation: As with any pain-management technique, it’s crucial to consult with a healthcare professional about your symptoms. They can provide tailored advice and may suggest complementary therapies or treatments.

While the act of placing a pillow between your legs might seem too simple to make a difference, it can, in fact, provide significant relief for some sciatica sufferers. By promoting spinal alignment and reducing muscle tension, it can be a helpful tool in one’s arsenal against the discomforts of sciatica. However, as always, individual experiences may vary, and it’s essential to combine this with other treatments and consult with a healthcare professional.

Which sleep positions are best for sciatica?

Sciatica can be quite discomforting, and choosing the right sleep position can make a significant difference in pain levels and quality of sleep. While the best sleep position varies from person to person depending on the root cause of their sciatica and their comfort preferences, certain positions are generally considered to be more beneficial for alleviating sciatic pain. Here are some recommended sleep positions for individuals with sciatica:

  1. Side Sleeping with a Pillow Between the Legs:
    • This is one of the most recommended positions for sciatica sufferers.
    • Lie on the side that doesn’t cause pain. If both sides cause pain, lie on the side that feels more comfortable.
    • Place a pillow between your knees to keep your spine, pelvis, and hips aligned. This position can help prevent the top leg from pulling the spine out of alignment, potentially exacerbating sciatic pain.
  2. Fetal Position:
    • Similar to side sleeping, curl your legs toward your chest in a fetal position.
    • This position can open up the spaces between the vertebrae where the sciatic nerve exits the spine, especially beneficial for those with a herniated disc, a common cause of sciatica.
  3. Sleeping on the Back with a Pillow Under the Knees:
    • Lay flat on your back and place a pillow under your knees.
    • This helps maintain the natural curve of your lumbar spine and reduces the pressure on the sciatic nerve.
  4. Reclined Position:
    • For some people, slightly reclining the upper body can help. This position can be especially helpful for those with sciatica caused by spinal stenosis.
    • If you have an adjustable bed, reclining it to a comfortable angle may help. If not, propping yourself up with several pillows might also work.
  5. Avoid Stomach Sleeping:
    • While some people might find relief in this position, stomach sleeping can strain the neck and the lower back. It might not be the best choice for most sciatica sufferers.
  6. Use of Proper Mattress and Pillows:
    • While not a sleep position, the firmness and support of your mattress can play a role in relieving sciatic pain. A medium-firm mattress is often recommended.
    • Additionally, using supportive pillows can help maintain proper alignment and reduce strain.

Remember, everyone is different, and the best sleep position for one person might not work for another. It’s essential to listen to your body and find the position that offers the most relief for you. If you’re unsure or if your pain continues, consulting with a physical therapist or another healthcare professional can provide guidance tailored to your specific situation.

Frequently Asked Questions

I’ve always been a stomach sleeper. Is there any way I can adjust my position to make it suitable for sciatica?

While stomach sleeping isn’t typically recommended for sciatica sufferers due to the strain it can put on the neck and lower back, if you must sleep on your stomach, consider placing a thin pillow under your pelvis and lower abdomen. This can help align the spine better. However, it’s still a good idea to try and transition to one of the more recommended positions for longer-term relief.

How long will it take to notice relief once I change my sleep position?

It varies for each individual. Some might experience relief immediately on the first night, while others might need a few days or weeks to notice significant changes. Consistency is crucial. If after several nights you don’t notice any improvements, consult with a healthcare professional to ensure that there aren’t other underlying issues or to receive tailored advice.

Can I use regular pillows to prop my knees or should I invest in specialized orthopedic pillows?

While regular pillows can certainly provide relief and are better than nothing, specialized orthopedic or memory foam pillows are designed to maintain their shape and offer consistent support throughout the night. If sciatica is a recurring issue, it might be worthwhile to invest in a pillow designed specifically for this purpose.


Dealing with sciatica can be a challenging experience, especially when it comes to finding a comfortable sleeping position that doesn’t exacerbate the pain. By understanding and trying out recommended sleep positions, individuals can find a setup that offers relief and promotes restorative sleep. Remember, while these positions can help manage and alleviate the pain, it’s essential to address the root cause of sciatica and consult with healthcare professionals for comprehensive treatment and care. Your comfort and well-being are paramount, and with the right strategies, a pain-free night’s sleep is within reach.
