The sacroiliac joint is a joint that is located at the very lowest part of the lower back. Pain coming from the SI joint will be felt in the lower back, buttocks, groin, and upper legs. The pain usually comes about when lifting a heavy object then twisting and may result immediately with a sharp pain in the lower back. Women are prone to injury in this joint because the ligaments are made loose by the hormones of pregnancy and by the shape of their pelvis. SI may be the cause of as much as 50% of all back pain. Even though this is one of the most common causes of lower back pain, many highly trained pain physicians cannot and do not treat this joint pain because it is difficult to see and access even with the use of fluoroscopy. This a specialty at Brier Creek Integrated Pain & Spine where fluoroscopic visualization and the treatment of this joint using test injections and radiofrequency ablation has been advanced.
This is a rare complication that may occur if a small hole is made in the fibrous sac and does not close up after the needle puncture. These small holes are only made in less than 1% of epidural injections and usually heal on their own. The spinal fluid inside can leak out, and when severe, the brain loses the cushioning effect of the fluid, which causes a severe headache when you sit or stand. These types of headaches occur typically about 2-3 days after the procedure and are positional - they come on when you sit or stand and go away when you lie down. If you do develop a spinal headache, it is OK to treat yourself. As long as you do not feel ill and have no fever and the headache goes away when you lay down, you may treat yourself with 24 hours of bed rest with bathroom privileges while drinking plenty of fluids. This almost always works. If it does not, contact the radiologist who performed the procedure or your referring physician. A procedure (called an epidural blood patch) can be performed in the hospital that has a very high success rate in treating spinal headaches.
