Sciatica in pregnancy
Léa Guido
Why does sciatica appear during pregnancy?
During pregnancy, weight gain, hormonal changes, and a shifting center of gravity alter the curve of the lower spine. This can irritate the sciatic nerve, causing pain that runs from the lower back down the leg.
Most common symptoms
Pain usually shows up in the lower back and buttock, radiating down the thigh and leg. Tingling, a feeling of heaviness in the affected leg, and discomfort from sitting or standing too long are also common.
Is it good to walk with sciatica during pregnancy?
Yes, walking at a moderate pace helps keep the spine mobile and improves circulation. It's best done in comfortable shoes, avoiding uneven surfaces, and resting as soon as the first discomfort appears.
How to relieve sciatica during pregnancy
Gentle chiropractic adjustments adapted to pregnancy can help reduce pressure on the sciatic nerve. Combined with specific stretches, a good resting position (on your side, with a cushion between your knees), and local heat, most expectant mothers notice gradual relief.
Frequently asked questions
Does sciatica in pregnancy affect the baby? No. Sciatica is a musculoskeletal discomfort affecting the mother and does not affect the baby's development.
At what point in pregnancy does it usually appear? It's most common from the second trimester onward, when the weight of the uterus begins to noticeably change posture.
Can I exercise if I have sciatica? Yes, as long as it's low-impact and suited to your situation. Walking, gentle swimming, and prenatal yoga are usually well tolerated.
Does it go away after giving birth? In most cases yes, though it can linger for a few weeks while the body regains its usual alignment.
When should I see a professional? If the pain is intense, doesn't improve with rest, or comes with loss of strength in the leg, you should be evaluated as soon as possible.
