Pregnancy often comes with its own set of challenges. One such challenge that many pregnant women face is sciatica, which can present with various symptoms, sometimes including lower back pain. While sciatica is not uncommon, you can usually continue your favorite activities pain-free with a little modification. This is where physical therapy comes in - your therapist can tailor a treatment plan to help relieve sciatic pain that is safe for both you and your baby. We consider it a privilege to help our pregnant clients at EW Motion Therapy continue their favorite activities throughout pregnancy while managing pain and limitations. You may decide that our program doesn’t fit your needs, but you can still read on as we provide an overview of sciatica and explain why it is common during pregnancy. We will highlight the symptoms to watch out for, discuss general treatment options, and delve into how physical therapy can be a crucial component in managing and relieving sciatic pain.

 

 

What is sciatica?

Sciatica refers to 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. Typically, sciatica affects only one side of your body. There are multiple causes of sciatica, which can lead to inflammation, pain, and often some numbness, tingling, or burning in the affected leg. Here are some common causes: 

 

  1. Herniated disk: A disk in the spine that bulges out and presses on the sciatic nerve.
  2. Spinal stenosis: Narrowing of the spinal canal, which can compress the sciatic nerve.
  3. Piriformis syndrome: When the piriformis muscle in the buttocks irritates or compresses the sciatic nerve.
  4. Degenerative disk disease: The breakdown of spinal disks that leads to nerve irritation.
  5. Spondylolisthesis: A condition where one vertebra slips over another, potentially compressing the sciatic nerve.
  6. Injury: Direct injury to the lower back or sciatic nerve area.
  7. Pregnancy: Increased weight and changes in posture can sometimes compress the sciatic nerve.

 

Why is sciatica common during pregnancy?

Sciatica is relatively common during pregnancy for several reasons. As the uterus expands, it can put pressure on the sciatic nerve. Additionally, pregnancy hormones, such as relaxin, cause the ligaments in the pelvis to relax and the spine to become less stable. This can lead to a change in posture and a shift in the center of gravity, both of which can contribute to sciatic pain. Furthermore, the fluid retention and increased blood volume associated with pregnancy can place extra stress on the spine and the nerve as it passes through the pelvis, exacerbating sciatica symptoms.

 

Symptoms of sciatica in pregnant women

The symptoms of sciatica can vary but often include:

 

  1. Lower back pain: Pain that starts in the lower back or pelvis and radiates down the buttock and back of one leg. This can present as a dull ache or a sharp, shooting pain.
  2. Numbness or tingling: A tingling or "pins and needles" sensation in the leg, foot, or toes.
  3. Weakness: Weakness in the affected leg or foot, making it difficult to move or stand.
  4. Difficulty sitting/standing: The pain may make it difficult to sit or stand for long periods.

 

These symptoms can be intermittent or constant and may vary in intensity from mild discomfort to severe pain that hinders daily activities. Lower back pain alone does not indicate sciatica, but a combination of the above symptoms is typically what leads to an official diagnosis from a doctor.

 

Treatment options for sciatica during pregnancy

Managing sciatica during pregnancy requires a careful approach to ensure the safety of both mother and baby. Here are some general treatment options:

 

Rest and activity modification

Rest and avoid activities that exacerbate sciatic pain. Listen to your body, and stop any activity that is causing pain. Low-impact activities like walking or swimming can help keep the body active without putting undue strain on the back.

 

Heat and cold therapy

Applying ice and heat to the affected area can help reduce inflammation and alleviate pain. Alternating between heat and cold can provide relief by relaxing the muscles and reducing nerve irritation.

 

Proper posture and ergonomics

Maintaining good posture is crucial in managing sciatica. Pregnant women should be mindful of their posture when sitting, standing, and sleeping, changing positions frequently. Using supportive pillows and maintaining a neutral spine alignment can help minimize pressure on the sciatic nerve.

 

Over-the-counter pain relief

Some over-the-counter pain relievers, such as acetaminophen, may be safe to use during pregnancy, but it is essential to consult a healthcare provider before taking any medication.

 

How can physical therapy help relieve sciatic pain?

Physical therapy can play a significant role in managing and relieving sciatic pain during pregnancy. Here’s how:

 

Customized exercise programs

A physical therapist can design a customized, safe exercise program tailored to your needs. These exercises can help strengthen the muscles that support the spine, improve flexibility, and reduce pressure on the sciatic nerve. Gentle stretching exercises can also help alleviate muscle tension and improve overall mobility.

 

Manual therapy

Manual therapy techniques, such as myofascial release and soft tissue mobilization, can help reduce muscle tension, improve circulation, and alleviate pain. A physical therapist can use these techniques to target specific areas affected by sciatic pain, providing much-needed relief.

 

Education and postural training

Physical therapists can educate pregnant women on proper body mechanics and postural alignment. Learning how to move safely and maintain good posture can help prevent further irritation of the sciatic nerve. They can also provide advice on how to modify daily activities to reduce strain on the back.

 

Pelvic floor therapy

Pelvic floor therapy can be particularly beneficial during pregnancy. Addressing dysfunction in the pelvic floor muscles can improve stability and reduce pressure on the lower back and sciatic nerve. A physical therapist who has knowledge of how the pelvic floor works can guide pregnant women through safe and effective pelvic floor exercises.

 

Aquatic therapy

Exercising in water can be a gentle and effective way to manage sciatic pain. The buoyancy of water reduces pressure on the joints and spine, allowing for pain-free movement and strengthening exercises. This can be particularly beneficial for pregnant women as it provides a low-impact environment for exercise.

 

Sciatica during pregnancy is not uncommon, but it’s not something you have to accept—there are strategies pregnant women can employ to manage their pain effectively. General treatment options such as rest, activity modification, and proper posture can provide relief, while physical therapy offers a targeted approach to alleviating sciatic pain and improving overall well-being.
