question: i had an mri which shows disc desiccation and scoliosis. need to know if scoliosis is the cause of my disc problems or is the disc problem due to scoliosis. I am a letter carrier (mail man) been on the job since 2005. Very labour intensive. The satchel is designed to distribute all the weight I carry on my back rather than on my shoulders. In 2003 i had an xray showed my lower back was normal. Are these present problems job related?
