💥 Not every radiating pain comes from muscles. And not every case is a herniated disc.
For years, it has been widely believed that if pain radiates into the leg or groin, the culprit must be either a disc problem or the muscles.
That is not always the case.
One structure that is very often overlooked is the iliolumbar ligament. Although small, it plays a crucial role in stabilizing the junction between the lumbar spine and the pelvis. When it becomes overloaded or restricted, it can produce symptoms that closely resemble sciatica or a herniated disc.
Do any of these symptoms sound familiar?
✅ Pain when standing up from a chair or changing position.
✅ Pain around the lumbosacral junction.
✅ Pain radiating into the buttock and the back of the thigh.
✅ Pain radiating into the groin and, in men, even into the testicle.
✅ Sometimes pain at the front of the thigh extending down to the knee.
✅ Restricted hip mobility and pain when lifting the leg.
In my clinical practice, I have repeatedly seen patients who were treated for muscle problems or intervertebral disc disorders for a long time, while the true source of their pain turned out to be the ligaments.
This is another example showing that manual therapy should not focus exclusively on muscles. The body also consists of ligaments, joint capsules, fascia, nerves, and many other structures that can generate pain—often radiating pain that can be very misleading.
Have you ever experienced pain that was treated for a long time as sciatica or a disc problem, only to discover later that the actual cause was something completely different?
