Low back pain isn’t always coming from your spine.
The sacroiliac joint (SIJ) connects your spine to your pelvis and plays an important role in transferring forces between your upper and lower body. When this joint becomes irritated or isn’t moving well, it can lead to pain in the lower back, buttock, hip, or even down the leg—often mimicking other conditions.
Common signs of SIJ dysfunction may include:
• Pain on one side of the lower back or buttock
• Discomfort with standing, walking, or changing positions
• Pain when climbing stairs or getting out of a chair
• A feeling of instability through the pelvis
The good news? SIJ dysfunction is often highly treatable with the right diagnosis and treatment plan. Physical therapy can help improve mobility, restore strength, address movement impairments, and get you back to doing the activities you enjoy.
