It seems there is degeneration changes in the vertebre which has been made evident and might me more symptomatic after episode of trauma.
Have you ever had similar kind of backache before? Any history of low backache?
If actual symptomatic nerve root impingement occurs, two days of absolute bed rest is indicated. If that does not solve the problem, then surgical excision is indicated.
Surgical excision is performed for impingement-documented sciatica that is unresponsive to 2 days of absolute bed rest.
The investigations are meant as pre operative workup to check for the important parameters.
