Have you had an MRI to ensure there is no spinal damage? If there isn't and the SI joint is just jammed, I would definately try a chiropractor before getting any injections. My pelvis is twisted to the right. I have constant SI joint pain-I have been seeing an Ortho for 2 1/2 years now & he has just recently written me off, because now I have started having this burning pain in both feet and legs. Now after all this time, he suggests I just go see a chiropractor. So I ask around and everyone I asks refers me to the same one in town. I am currently seeing him now. He tells me he can fix the pelvis, & it will probably take the burning pain away in my legs-IF-he says I dont have damage from the injections. Yesterday, I was reading about this on some website that tells me if the doctor hits a nerve root then it will cause a burning pain in the legs-Now I am thinking that may be what has happened to me. Those injections are dangerous. I would at least try the Chiropractor to see if he can adjust it and put it back in place-it will be worth it, if he can. On the otherhand, if you don't try it, my husband fractured his spine and they were trying the injections before they did surgery, however they didnt help and he ended up getting a back fusion & is still in just as much pain as before the surgery. The doctor he was seeing was an Ortho & Neurosergeon both-had been to school for both-But from what I understand, they both will do the injections-a Neuro or Ortho. But if I was you, and the problem was a dislocation as you say, I would see the Chiropractor first. I wish someone would have told me this before I had all those injections. When I was asking around about a referral to the chiropractor, my cousin, who was in a bad car wreck a few years ago, said that her pelvis was jammed to and that the chiropractor fixed her, & that every once in a while it will start hurting again & she just goes back a few times & she is good to go for a year or so. Hope this helps
