Sciatic Nerve Pain During Pregnancy: Causes and Treatment

The sciatic nerve runs under your uterus to your legs. Sciatic nerve pain during pregnancy is thought to be associated with pressure on the nerve caused by the developing baby.
The sciatic nerve is the largest nerve in the body, providing a sensory and motor function to the lower extremities. This nerve provides sensation to the back of the thigh, the lower part of the leg and the sole of the foot. Sciatic nerve pain is a periodic severe pain that occurs throughout your legs.

What are the safe treatments?

The simplest remedy to sciatic nerve pain while pregnant is to lie on your side, opposite of the pain.  This may help relieve the pressure on the nerve. Avoid heavy lifting and minimize standing for long periods of time. If you experience pressure while standing, try elevating one foot and resting it on something. Swimming may also ease discomfort.
You may experience relief by applying heat or cold to the troubled area. Your healthcare provider may recommend acetaminophen to relieve the pain.
It is important to contact your health care provider if the pain becomes constant, or increases in severity or frequency.
