Pregnancy & Sciatica Pain

Possible Causes of Sciatica Pain Due to Pregnancy


Pregnant women are prone to a number of little aches and pains caused by the changes in their hormones and the added weight they are forced to carry. Back pain is especially common, as the lower and upper back experience considerable extra pressure from the weight in the front of a woman's stomach and additional weight spread out throughout the body.

While some lower back pain is common, some lower back pain is atypical, but can lead to more severe symptoms. When the pain appears more severe, it may be sciatica.

Typically sciatica occurs during the third trimester of pregnancy. Since sciatica is a set of symptoms, rather than a diagnosis, it may be caused my several different conditions related to your pregnancy that cause pressure on your sciatic nerve:

  • Baby Size
    In some cases, sciatica symptoms may be caused by the baby shifting positions into one that is more suitable for birth. The resting place for the baby, coupled by the increase in the baby's size, may cause it to put pressure on the lower sciatic nerve leading to sciatica symptoms.

  • Herniated DiscsThe pressure from the increase in baby weight may already be causing problems with your spine. If you lift or move too quickly, you may add pressure that creates a slipped disc, which can increase spinal pressure against the sciatic nerve.

What is the Experience of Sciatica Like in Pregnant Women?

Pregnancy sciatica has the same symptoms as all other types of sciatica, since it is not a pregnancy specific condition – rather, it is simply a pregnancy risk. Some of these symptoms include:

Pain that feels as though it is radiating through your buttocks and legs, typically on one side:

  • Tingling or numbness in the legs that may tingle or feel like a needle sensation.

  • Tingling or numbness in the legs that may tingle or feel like a needle sensation.

Pregnant women are especially advised to seek help if the pain causes difficulty moving the legs, as though they are too weak to move.

Will the Pain Go Away?

Sciatica pain can be treated, and may go away on its own. Sciatica pain due to the location of the baby in the womb generally goes away when the baby moves. If the pain does not seem to disperse, or if there are any concerns, it is a good idea to seek help.
