"Understanding Sacro-Iliac Joint Pain: Causes and Symptoms"

Sacroiliac joint pain, also known as SI joint pain, is a condition characterised by discomfort or pain in the sacroiliac joint, which is located in the pelvis. This joint connects the sacrum (the triangular bone at the bottom of the spine) to the iliac bones (the large bones that form the pelvis). The sacroiliac joint plays a crucial role in transferring the weight of the upper body to the lower body during activities such as walking, standing, and lifting.

Symptoms of sacroiliac joint pain can vary from person to person but often include:

  • Lower back pain: Pain may be felt on one side or both sides of the lower back, typically around the buttocks and may radiate down the leg.

  • Pain in the buttocks: Discomfort or sharp pain may be felt in one or both buttocks, often aggravated by sitting for extended periods or standing up from a seated position.

  • Hip pain: Pain can be felt in the hip area, particularly on the side where the sacroiliac joint is affected.

  • Stiffness and reduced mobility: Patients may experience stiffness in the lower back, hips, and pelvis, leading to difficulty in performing daily activities like bending, twisting, or lifting.

  • Pain worsened by certain activities: Activities that involve twisting, bending, or lifting heavy objects may exacerbate sacroiliac joint pain.

Several factors can contribute to sacroiliac joint pain, including:

  • Trauma or injury: Injuries such as falls, accidents, or sudden impacts can strain or injure the sacroiliac joint, leading to pain and discomfort.

  • Pregnancy: Hormonal changes during pregnancy can cause ligaments around the sacroiliac joint to loosen, leading to increased mobility and potential pain.

  • Arthritis: Inflammatory conditions such as ankylosing spondylitis or osteoarthritis can affect the sacroiliac joint, causing pain and stiffness.

  • Degenerative joint disease: Wear and tear of the sacroiliac joint over time can lead to degenerative changes, resulting in pain and dysfunction.

It's important for individuals experiencing symptoms of sacroiliac joint pain to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan tailored to their specific needs.
