Get a back brace (those things the guys at Home Depot wear). I stole mine from my days at KMart lol. I use it sometimes around the property.
But damn, that sucks man. Be careful, you don’t want to screw your back up like I did. I can’t lift anything over 50lbs for more than 20 minutes before it tightens up on me and I have to take a break for 20 before it stops hurting. Even basketball and crap…I can’t be bent over in a dribbling position for more than 20-30 minutes.
