I have considerable lower back pain, also numbness in left buttocks and down left leg, girdling at the upper thigh. MRI shows "Small protrusiton of L3-4 interv. disc on left far laterally with annular fissuring fesulting in mild left neural foraminal narrowing with slight posterolateral displacement of the exiting l3 nerve root." Other mild bulges L4-5 w/ fissuring, and mild buldge L5-S1. 1) does this explain symptoms 2) I have a plane/car trip in 2 days lasting 8 hrs, then other travel. Will this be harmful?
