Chiropractic During Pregnancy Because of increased pressure in the lumbar spine, it is common for pregnant women to experience low back pain with associated leg pain (sciatica or radiculitis). Due to concerns for the fetus, medical doctors will not prescribe pain medications. Many local OBGYN physicians have referred their pregnant patients to our office for relief of low back pain. Dr. Williams has had great success helping pregnant women find relief of their low back pain due to pregnancy. He also offers follow up care after pregnancy.
