I applied for SSDI and they keep sending me to ridiculous Dr.'s. Does anyone know why?

I have scoliosis, a fused spine, degenerative disk disease, spinal stenosis, bulging disks, spinal arthritis, and pressure being put on several nerves including the sciatic by my spine. I have monthly dr. appointments and x-rays and MRIs that prove all of this and more. Why do they keep sending me to Dr.s that don't know a single thing about my condition or the spine and keep telling me falsehoods about my condition?!
