Chronic Sacroiliac Pain Symptoms

Chronic Sacroiliac Pain Symptoms

The Sacroiliac (SI) joints connect the lower end of the spine to the pelvic bone. The sacrum is located at the base of the spine and the iliac bones form the pelvis. The ilium, as a part of the SI joint offers support to the sacrum, which in turn gives structural support to the spine.

There is little movement at the SI joints. As these joints need to bear the weight of the upper body when we are standing up or walking, they are under stress most of the time.

Inflammation of the SI joints can occur due to a number of reasons. Injury to the buttocks or pelvic region, a road vehicle accident or lifting heavy weights in an improper way can cause the connective tissues surrounding the SI joint to tear. When the cartilage layer between the SI joint gets damaged, the bones begin to degenerate as a result of constant grinding against each other.

At the time of pregnancy, certain hormones are released in the body to loosen-up the ligaments of the pelvic area so as to prepare it for child birth. These hormones tend to relax the ligaments of the SI joints too, causing too much movement in the joints and wearing them down. Different types of arthritis are also responsible for chronic sacroiliac pain.

The most common symptom of SI joint pain is lower back pain. Sometimes, patients may also complain of stiffness. The pain begins on one side, but can spread to the other side of the back, too. The pain may extend to the groin, thighs or buttocks. At times, it may be difficult to spot the source of the pain.

The pain may not even be moderate in the beginning, but some activities may worsen it. People may feel a sharp pain when they try to stand up, especially after sitting for a long time.

Walking and climbing stairs may be painful too. Basically, it may hurt whenever your upper body puts weight on the SI joints, such as, sitting, standing, lifting weight, kneeling, squatting, and bending forward or backward. Lying down may feel the most comfortable, but turning sides or rolling may be a bit harder than usual. Some people may experience a burning sensation in the pelvis.

If there are other disorders affecting the SI joint, then there could be additional symptoms as well. For instance, enclosing spondylitis could cause rectal bleeding and diarrhea.
