When you have the MRIS of your spine done, was it done with Contrast at a reputable hospital with a decent MRI Machine and were they looking for anything specific?
Reason I ask is well sometimes MRI machines suck. Sometimes you have to go somewhere else that has a better machine. Some are better than others and well if they are looking for MS
They usually will use MS protocol. They might look at you crazy when you know that but its true. MS sometimes doesn't show up on MRIs too. Sometimes the lesions can take while to appear and be gone within a short time. Sometimes if the MRI machine is weak they miss something in the Spine that can cause that. Given the fact they were working and suddenly dont work anymore sounds like a spinal injury that was suddenly made worse. I'm not a Dr. though I just know that sometimes those Machines can miss things. Definitely have repeat MRIs done at some point. Don't ever go off of one and be done. Because Lesions on the spine and the brain can appear and disappear. Are you only seeing your family Dr. or have you seen a Specialist?
