Hip and Lower Back Pain During Pregnancy at Night (Causes + Relief Tips)
Hip and lower back pain during pregnancy is extremely common, especially at night in the second and third trimester. As your body changes, sleeping comfortably can become harder — but the right support and sleep setup can make a big difference.
If you’re struggling with discomfort at night, small adjustments to your sleeping position and support can help you sleep more comfortably.
Every pregnancy is different, so experiment to find the positions that feel best for you. If you want to read more about sleeping positions you can read this blog.
Why hip and lower back pain happens during pregnancy
Pregnancy naturally changes how your body feels and moves:
Hormones loosen your joints
The hormone relaxin makes ligaments softer to prepare for birth, but it can also make your hips and lower back feel unstable or sore.
Your body weight and posture shift
As your baby grows, your center of gravity moves forward, adding pressure to your spine and pelvis.
Side sleeping pressure builds up
Sleeping on your side for long periods can create pressure on the hip against the mattress.
Daily strain adds up at night
Your muscles work harder all day to support your growing belly, which can lead to tension when you finally rest.
