Pain coming from the SI (sacroiliac) joint
SI joints link the sacrum with the pelvic bone. They enable us to hold our body straight during walking and standing and transfer our weight to the legs.
How does the pain manifest itself?
- It is most often a sharp pain localised to the posterior part of the joint and in the middle part of the gluteal muscles, which can radiate to the inguinal area, the posterior part of our thighs, sometimes all the way down to the knees.
- It manifests itself during sitting, during forward bending or longer periods of sitting in the car, during standing, walking up the stairs, getting out of the car and during rest. Sometimes the pain gets better during walking.
