Posterior Pelvic Pain (Sacroiliac Joint Pain) PPP

Posterior pelvic pain during pregnancy pain felt at the back of the pelvis, around the sacroiliac (SI) joints.

Often described as deep and sometimes radiating to the buttocks and posterior thigh. It occurs in about 20% of pregnancy cases.

Posterior Pelvic Pain

The Posterior Pelvic pain result from stresses on the sacroiliac joints brought about by the increase in weight during pregnancy. Further worsened by SI dysfunction.

The sacrum, innominate, and their ligamentous connections, which make up the SI joint, grow lax during pregnancy. Sacroiliac joint laxity and the widening of the symphysis pubis will cause the pelvis to be ‘lop-sided’.

As the uterus enlarges, increased low back spine curvature, along with ligamentous laxity, can cause significant mechanical strain on the sacroiliac joints, resulting in a deep ache in the posterior pelvis.

Posterior Pelvic Pain Symptoms

When asked to locate your pain, you might sweep your hand over your entire pelvic area rather than point to a single spot. You might describe your chronic pelvic pain in one or more of the following ways:

  • Severe and steady pain
  • Pain that comes and goes (intermittent)
  • Dull aching
  • Sharp pains or cramping
  • Pressure or heaviness deep within your pelvis
