Acupuncture for SI Joint Pain in Pregnancy

Acupuncture is a safe and effective treatment for SI joint pain in pregnancy. When treating a pregnant patient with SI joint pain, certain points help to release tense ligaments and muscle tissue that causes pain and restriction. A combination of local points as well as distal points can be used. We often lay patients on their sides or use a pregnancy massage pillow to lay them down. A certain number of treatments is given to effectively reduce and eliminate pain. We also give our patients stretching exercises to do at home to help them get pain free.

What SI Joint Pain in Pregnancy Feels Like

SI joint pain usually sits low in the back, just to one side of the spine, over the dimple at the back of the pelvis. It can be a dull ache or a sharp, catching pain, and it often travels into the buttock, the hip or the back of the thigh. Most women notice it more when they:

• Roll over in bed or get in and out of the car
• Climb stairs or stand on one leg to get dressed
• Walk for a long time, especially on hard New York City pavements
• Stand up after sitting for a while

It is different from general low back pain, which sits higher and across the middle of the back, and from sciatica, which runs down the leg below the knee with tingling or numbness.

Why SI Joint Pain Happens in Pregnancy

During pregnancy the body releases the hormone relaxin, which softens the ligaments of the pelvis so it can widen for birth. That extra movement is useful later, but it also means the two sacroiliac joints are less stable. At the same time, the growing belly moves your center of gravity forward, the lower back arches more, and the glute and hip muscles work harder to hold everything in place. When one side moves more than the other, the joint becomes irritated and the muscles around it tighten to protect it.

SI joint pain can start in any trimester, but it is most common in the second and third, and it is more likely if you had pelvic pain in an earlier pregnancy.

How Acupuncture Helps SI Joint Pain During Pregnancy

Acupuncture works on SI joint pain in three ways. It reduces local inflammation around the joint, it releases the glute, hip and lower back muscles that guard the area, and it calms the pain signal itself so the body can move more normally. Many patients feel looser and lighter walking out of the first session.

In Chinese Medicine, pregnancy draws heavily on the body’s Blood and Kidney energy, which nourish the lower back and joints. Treatment supports these while easing the local blockage, so it addresses both the pain and the reason the area is struggling.

Acupuncture Points Used Safely in Pregnancy

Pregnancy acupuncture uses a restricted point selection. A licensed acupuncturist trained in prenatal care avoids points that are traditionally considered stimulating to the uterus before full term, and chooses gentle local points around the low back, sacrum and hip, along with distal points on the legs and hands. Needles are shallow and few, and you are treated lying on your side, supported with pillows, rather than on your stomach. Electroacupuncture and strong cupping over the low back and abdomen are not used in pregnancy.

How Many Sessions Will I Need?

Most women come weekly at first. Many notice a clear difference within two to four sessions, and a course of four to six weekly treatments is common, followed by sessions every two to three weeks as the pregnancy progresses. If the pain returns in the third trimester, treatment can be stepped up again and combined with labor preparation sessions from around 36 weeks.

Simple Ways to Ease SI Joint Pain at Home

• Keep your knees together when you roll over in bed or get out of the car.
• Sleep with a pillow between your knees and ankles to keep the pelvis level.
• Avoid standing on one leg: sit down to put on pants, socks and shoes.
• Take smaller steps and break up long walks and stair climbs.
• Try a pelvic support belt for long days on your feet.
• Gentle movement such as cat-cow, pelvic tilts and glute bridges, once your provider has cleared you for exercise.

A prenatal physical therapist can also assess the joint and give you a tailored exercise plan. Acupuncture works well alongside physical therapy.

When to Call Your OB or Midwife

Call your provider before your next acupuncture visit if back or pelvic pain comes with fever, bleeding, fluid leaking, regular tightening of the belly, pain that comes and goes in waves, or numbness or weakness in the legs. These need medical attention first.
