What is the english term for "Belet Ba Disc" ?

Hi :) I'm currently in New-Zealand, thinking about doing a sky-dive. I was wondering if this is dangerous for me since 2 years ago I got diagnosed with "Belet ba disc" in L4-L5 (or something like that)... I want to ask here locally if this is safe, so I need to know the MEDICAL term for this condition... I hope to get an answer pretty soon :) THANKS IN ADVANCE Eitan

The medical term is bulge disc AND from what you said I dont see any problem doing such activity.
