I have had lower back pain and sciatica for almost a year now and have a new kind of pain in the last month. All along the pain has been behind me, back, back of legs, buttocks... all in the back. But in the last month the pain is in my outer hips and the front of my thighs down to my knees. It shoots and burns just like the sciatic pain but my understanding is that sciatica only goes down the back... so what is this pain in the front? Is this what SI joint pain is like? It is really bad and keeps me from doing much; even less than before. Walking brings on alot of pain so I'm not even doing much of that now. My doctor said the CT scan showed the herniation was not causing any nerve impingement but that doesn't make any sense to me, especially now. Hopefully the MRI next month will tell what is going on.
