I had an MRI a few years ago on my stomach to locate cysts and endometriosis and had no problems. I just had another MRI a few weeks ago on my hips and spine and that same night I had unbearable pain in my hips. It felt like stabbing pain deep in my bones. It was horrible. I don't know why this happened but will ask my pm dr when I see him next week. Not sure if anyone will know but it can't hurt to ask. I think it's related to rsd. I don't know why, but I just do. I have osteopenia and osteoarthritis in my hips that are causing me alot of stiffness and external pain , but the pain I had in my hips after the MRI was different. It was that deep aching pain. It only lasted one night but I'll never forget it. It was really scary.
