Sciatic Nerve Pain in Pregnancy
The short answer
Sciatica during pregnancy involves pain that radiates along the sciatic nerve, from the lower back through the buttock and down the leg. It affects roughly 1% of pregnant people and is caused by the growing uterus putting pressure on the sciatic nerve, hormonal changes loosening joints, or the baby's position.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
Sciatica may begin in the second trimester as the uterus grows and weight increases. The pain typically radiates from the lower back or buttock down one leg and may feel like burning, tingling, or numbness. Gentle stretching, prenatal yoga, warm compresses, and sleeping on your side with a pillow between your knees can help manage symptoms.
Sciatica is most common in the third trimester when the baby's weight puts the most pressure on pelvic nerves. The baby's head can rest directly on the sciatic nerve. Swimming, prenatal physical therapy, and pelvic tilts may provide relief. Avoid prolonged sitting or standing. A maternity support belt can help distribute weight more evenly.
Sciatica usually resolves after delivery once pressure on the nerve is relieved. If pain persists beyond a few weeks postpartum, talk to your provider. Gentle core strengthening exercises and physical therapy can support recovery.

Back Pain During Pregnancy
Back pain affects approximately 50-70% of pregnant people and is most common in the second and third trimesters. It is usually caused by the shifting center of gravity, weight gain, hormonal changes that loosen ligaments, and postural adjustments as the belly grows.
Hip Pain During Pregnancy
Hip pain affects many pregnant people, particularly in the second and third trimesters. It is caused by the hormone relaxin loosening hip joints, weight gain changing your gait, the growing belly shifting your center of gravity, and the pressure of side sleeping. It is usually treatable with stretching, support pillows, and gentle exercise.
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
20-Week Anatomy Scan Unexpected Findings
The 20-week anatomy scan checks your baby's major organs, structures, and growth. Most scans are completely normal. When unexpected findings are identified, they range from minor variants that resolve on their own to conditions that need further evaluation. Many findings require nothing more than a follow-up ultrasound to confirm the baby is developing well.
