Have odd story

About 7 weeks ago suffered acute debilitating pain in right hip and lower back and knee pain definitely with sciatica affiliations. Have had multiple disks problems in neck and lumbar. Mostly resolved. This came totally out of the blue no known reason. Pain so severe could not move laying down even worse. Had mri with no consult yet. As of right now pain is minimal . Am I crazy? How can something so bad disappear?
