Hi, thanks for writing to HCM. I can assure you that disc bulge with minimal thecal sac indentation is not at all a serious problem. So dont take hasty decisions to quit the job. You can comfortably travel without issues but with some precautions. Disc bulges may regress over a period of time if it is not subjected to mechanical stresses as like in bending forwards and lifting heavy weights, in which case they will get worsened causing disc prolapse. I suggest you to follow the below mentioned guidelines - * Use a lumbo sacral support while travelling * Avoid lifting heavy weights * Physiothearpy for back muscles strengthening * Ocassional analgesics /muscle relaxants * Avoid smoking - as this will cause early disc degeneration. Hope this helps
