Sciatica During Pregnancy: Chiropractic Care in Allen, TX
Sciatica during pregnancy is a sharp, burning or tingling pain that runs from your lower back or buttock down one leg. It's common in the second and third trimesters, as your pelvis loosens and your posture shifts to make room for your baby. At Trinity Life Chiropractic in Allen, TX, Webster certified Dr. Colton O'Brien offers gentle prenatal care that may help ease the pressure, alongside your OB or midwife.

Many moms-to-be call any pain that shoots down the leg "sciatica." Sometimes the sciatic nerve itself is irritated; more often the pain starts in the joints at the back of the pelvis or in the buttock muscles that sit over the nerve. Our prenatal chiropractic care in Allen is built for this stage: gentle, specific and planned around your pregnancy.
What sciatica during pregnancy feels like
It usually shows up on one side:
- A sharp, shooting or electric pain from the lower back or buttock down the back of the thigh, sometimes to the foot
- Burning, tingling or pins and needles in one leg
- A deep ache in one buttock or hip that's worse after sitting
- Pain that flares when you stand up, roll over in bed or climb stairs
Is it sciatica or pelvic girdle pain?
Not every pregnancy pain in the hips is sciatica. Pain across the front of the pelvis or at the pubic bone is usually pelvic girdle pain instead; our guide to pregnancy back and pelvic pain covers it. If you're not sure which you have, the exam at your first visit looks at both.
What causes sciatica during pregnancy?
- Relaxin. This hormone loosens the pelvic ligaments to prepare for birth[1], so the sacroiliac joints at the base of the spine can move unevenly.
- A new center of gravity. As your belly grows, your weight shifts forward[1] and the curve in your lower back deepens.
- Tight buttock muscles. The piriformis muscle works harder to steady a looser pelvis, and when it tightens it can press on the sciatic nerve beneath it.
- Your baby's weight and position, which add pressure in the pelvis later in pregnancy[2].
Less often, a bulging disc is the cause. That's why we start with a careful exam, and why the warning signs below matter.
What happens at a prenatal chiropractic visit for sciatica?
Your $150 prenatal first visit starts with a conversation: how far along you are, where the pain travels and what your OB or midwife has told you. Dr. O'Brien then does a gentle exam of your lower back, pelvis and hips, and runs quick, non-invasive INSiGHT nervous-system scans.
- A conversation about your pregnancy, your pain and your provider's advice
- A gentle exam of your lower back, pelvis and hips
- INSiGHT nervous-system scans
- A care plan recommendation, and your first adjustment if it's right for you that day
Can a chiropractor help sciatica during pregnancy? The Webster Technique
Care centers on the Webster Technique, a specific chiropractic analysis and adjustment for the pelvis and sacrum. Dr. O'Brien is Webster certified through the International Chiropractic Pediatric Association (ICPA). You're adjusted in positions that keep pressure off your belly, such as lying on your side or on pregnancy pillows, and adjustments are gentle and low-force.
Gentle care may help ease the pressure around the pelvis and the nerve, though every pregnancy is different and we can't promise how much it will help. We explain what we find and recommend a plan; you decide what's right for you. Not pregnant? See our page on sciatica care for adults, or our back pain chiropractor page for everyday low back pain.
Working alongside your OB or midwife
Chiropractic care doesn't replace prenatal medical care. We're glad to work alongside your OB or midwife, and if you'd like us to share what we found with them, just ask. If your pregnancy is high risk, or you've been asked to limit activity, check with your provider before your first adjustment. After your baby arrives, postpartum chiropractic care picks up where prenatal care leaves off, including care for postpartum back pain.
Safety first
When to call your OB or midwife first
Call your OB or midwife before chiropractic care, or 911 in an emergency, if you have:
- Numbness in your groin, inner thighs or between your legs, or new trouble controlling your bladder or bowels
- Weakness in a leg or foot, or a foot that drags or catches when you walk
- Back or pelvic pain that comes and goes in waves, or comes with cramping, tightening, bleeding[1] or leaking fluid
- Pain, swelling, warmth or redness in one calf or thigh
- Pain with a fever or burning when you urinate[1], or pain after a fall or other injury
- Back pain that is severe or lasts more than two weeks[1] (the advice of the American College of Obstetricians and Gynecologists)
How to ease sciatica during pregnancy at home
- Lie on the side opposite the pain, the simplest remedy the American Pregnancy Association suggests[2], with a pillow between your knees[1]. Read the American Pregnancy Association's guide (opens in a new tab) for more.
- Sit down to put on pants and shoes, and keep your knees together getting in and out of bed or the car.
- Change position often; short walks or a swim[2] usually beat long stretches of sitting or standing.
- Try a warm compress or a cold pack[1] on the sore spot.
- Ask your OB or midwife which stretches and pain relievers are right for you.
Questions about sciatica during pregnancy
Is chiropractic care safe for sciatica during pregnancy?
For most healthy pregnancies, care from a chiropractor trained in prenatal techniques is considered safe. Dr. O'Brien is Webster certified, uses gentle, low-force adjustments and adjusts you in positions that keep pressure off your belly. If your pregnancy is high risk, or you have bleeding or any warning sign on this page, talk with your OB or midwife first.
When does sciatica usually start in pregnancy?
Most moms notice it in the second or third trimester, as relaxin loosens the pelvis and the growing belly shifts weight onto the lower back and hips. Some feel it earlier, especially after back or hip pain in an earlier pregnancy. You don't need to wait for pain to start prenatal chiropractic care; many moms begin in the first trimester.
Will pregnancy sciatica go away after my baby is born?
For many women it eases in the weeks after birth, as hormones settle and the weight of pregnancy is gone. For others, low back or hip pain lingers while they lift, carry and feed a newborn. Mention it at your postpartum checkup; we also see moms after birth for postpartum chiropractic care.
Do I need a referral from my OB to see a chiropractor for sciatica?
You can book your first visit directly, online or by phone. At that visit we ask about your pregnancy, any complications and what your OB or midwife has advised, because we work alongside them. If your provider has asked you to limit activity, check with them before your first adjustment, and tell us what they said.
What does a prenatal first visit cost in Allen?
The prenatal new patient visit is $150 (regularly $350). It includes a consultation of 30 minutes or more with Dr. O'Brien, three INSiGHT nervous-system scans, a hands-on exam and, if it's appropriate that day, your first adjustment. You leave with a care-plan recommendation and no pressure to commit. Ask the office about insurance.
