Welcome to health care magic.
1.The spine shows degenerative changes - which can be age related or excessive usage or hard working individuals.
2.Straightening is due to the
nerve irritation with the disc causing pressure effect.
3.The disc looses hydration and causing bulging as mentioned in your case at different levels.
4.This is causing pressure effect on the exiting
nerve root, however its not so much serious at this point as the spinal chord involvement is not much mentioned in the report.
5.At this point you need rest, with back exercises and if no response
physiotherapy will be definitive for you. If any option to have new job please try.
Good luck.
Hope i have answered your query,
any thing to ask ? do not hesitate to ask.
