Well .... I did say I'd check it out for you .....
After surgery ... you are encouraged to get up and mobile ASAP... you will be advised how much you are and not allowed to do....to do light chores is ok, not to overdo anything, and to take one step at a time ...
I had a disc removed last year ... and I wasn't allowed to drive, or do any lifting for 6 weeks ... I can drive now .. but I still cannot lift anything too heavy, as I still get twinges, so I just don't do it ... I have to half all my washing, shopping etc ..so I can carry it ... ok I gotta do multiple trips up n down the stairs and from the car etc .. but it's good excersise!
You have 3 kids, they can help you out ... make it into a game if they are really young ...
I can't tell you how to run your life .. but if lifting and bending are essential in your job, please ask your boss if these jobs could be restricted, cos as you have already had a disc removed last year, you've already hurt yourself again this year, and undergoing surgery again ... you have already weakened your back. I hate to say it, but I really don't think you'd be able to do this kinda work all day everyday if you have to lift / bend etc ... ;-(
Sorry to be blunt, but you're health is paramount here...
