Physical Therapy For Sciatica: Ways To Ease Nerve Pain

Physical therapy is the first-line treatment for treating and relieving sciatica symptoms. Before we look at the ‘physical therapy for sciatica’, first understand what is sciatica and what are the causes this?

What is Sciatica?

The sciatic nerve is the largest nerve in the human body and is formed by the union of L4, L5, S1, S2, & S3. These five nerves go deep in the buttocks, near the front surface of the piriformis muscle down the back of the thigh, to the heel and sole of the foot.

Sciatica is caused when there is pinching or compression in the sciatic nerve by-

  • Disc herniation
  • Spinal stenosis or narrowing of the spine
  • Bone spur on the spine
  • Compression of the sciatic nerve by ‘wallet’ – pain caused by a large wallet while sitting
  • Piriformis syndrome
  • Increased risk with age, obesity, or diabetes.


  • Radiating pain from the lower spine to the buttocks and down the back of the leg
  • Difficulty in sitting, walking, & standing
  • Numbness and tingling in legs
  • Pain can vary from a mild ache to a sharp, burning sensation
  • Pain that gets worse with movement


Risk factors for sciatica:

  • AGE: Age-related changes in the spine is the most common cause of sciatica. As we age, the disc starts to degenerate which may cause it.
  • OBESITY: Excessive body weight increases stress on the spine. This can contribute to the compression of nerves and hence may cause sciatica
  • OCCUPATION: A job that requires heavy weight lifting, and back twisting might contribute to it
  • DIABETES: Diabetes can cause nerve damage which could be a reason for sciatica pain
  • PROLONGED SITTING: People with a sedentary lifestyle are more prone to develop sciatica than those with an active lifestyle
  • POOR POSTURE: It could be a big reason for developing sciatica. The slouched sitting position can put stress on the disc leading to sciatica pain.


Prevention of sciatica is not always possible. But taking some steps to protect your back can be beneficial.

  • EXERCISE REGULARLY: To keep your back strong, paying attention to your core muscles is very important. Both the muscles in your back and in your abdomen are very important for keeping the perfect posture.
  • MAINTAIN GOOD POSTURE WHILE SITTING: Choose a seat with good back support and with armrests. Place a small pillow behind your back to maintain the normal curve of the spine
    1. If you sleep on your back: Prefer a thin pillow under your head. Add 1 or 2 pillows under your knees may help ease back pressure
    2. If you sleep sideways: Place a thick pillow to support your head and neck. Also, add a pillow between your knees to keep your spine in neutral alignment.
    3. If you sleep on your stomach: You should put your head on a very thin pillow or directly on the mattress. Place a thin pillow underneath your pelvis to keep it back in alignment. But sleeping on your stomach should be avoided as much as possible due to the risk of neck strain.

Physical Therapy For Sciatica

When you diagnose with sciatica, physical therapy could help you in many ways. Many modalities like TENS, diathermy, traction, etc used in physical therapy are very beneficial for your sciatica pain.

Some at-home treatments as well as the treatment you can get at the physiotherapy clinic are described below:


Complete bed rest results in a loss of 1-3% of muscle strength per day. Therefore, no more than 2 days of absolute bed rest is recommended. Avoiding doing activities or just laying in bed can worsen your condition.

Applying ice pack

You should apply ice on the area of pain only during the first few days of symptoms.

For applying ice, wrap the ice pack or some ice cubes in a towel and then apply it over the affected area for a short interval of time.

This will reduce swelling and inflammation and may serve as a mild anesthetic.

Heat application

You should apply ice during the first 2-3 days of symptoms. After 2-3 days, switch to heat. Heat will help relax the muscles in your back. It will reduce muscle spasms and hence will reduce pain.


  1. Non-steroidal anti-inflammatory drugs (NSAIDs) are medications that are used to relieve pain, reduce swelling and inflammation. Medications such as aspirin, Advil, or ibuprofen can help you to reduce pain and inflammation.
  2. Muscle relaxants
  3. Corticosteroids: oral or injected

Deep heat (diathermy)

It will decrease spasms and pain, increase collagen distensibility. Usually used for sub-acute or chronic injury.

Ultrasound is most commonly used. Microwaves and shortwaves are rarely used because of increased risk and high equipment costs.


Tens (transcutaneous electric nerve stimulation) help to decrease spasm, pain, edema, inflammation, & atrophy. It increases circulation to help remove inflammatory byproducts.

It is best during the acute phase of injury.

Mechanical traction

Help to relieve pain by intervertebral distraction, stretching muscles, and other soft-tissue structures.
