I have had 2 microdiscectomy's on L5 S1 within 2 months of eachother at the end of 2007. I have been doing good ever since but the L4 that doctor had told me in '07 that was slightly bulged (and left alone during surgeries), seems to have severly gone wrong when i slipped down a step with socks on this past Tuesday. I have been in agony and unable to walk straight upwards. Feels like i herniated the L4 but have a MRI in the works with doctor. I am home from work and contemplating doctor options since my doctor is no longer in plan to do surgery just consulting. Need to find a new doctor in my plan. Do you think i will have to get a fusion now or just another discectomy? Guess i need to see what mri reads. What a dissappointment this has been. Very depressed and down and out. I have lot's of housework to do and vacations planned this year along with my wife expecting twins!!! Any advice will be greatly appreciated.
