Care at the Allen office: back pain, neck pain, pregnancy and kids
Allen families come in at every stage, from pregnancy to back pain. Each kind of care has its own page:
- Pregnancy: Dr. O'Brien is a Webster-certified prenatal chiropractor. Prenatal chiropractic is not a substitute for prenatal care from your OB or midwife; it works alongside it.
- After birth: postpartum chiropractic supports a new mom's back, hips and posture.
- Babies and kids: the pediatric chiropractor page covers newborns through teens.
- Adults: back pain, neck pain and headaches each have their own page: back pain chiropractor, neck pain chiropractor and chiropractor for headaches and migraines. Leg pain that starts in the low back is covered on the sciatica page, and the family chiropractor page covers care for the whole family, as complementary care alongside your doctor.
