Sometimes when I bend down, i feel a pain/discomfort in my lower back and stumble back up..what could it be?

Question

I'm 19.......I do have bad habits of sitting down crooked....or at work since i left heavy boxes sometimes I lift them the wrong way to be faster....this discomfort/pain lasts a split second and i have difficulty getting up, but when i do the pain/ discomfort is no longer there...AND it doesnt always happen..also it has been going on for a few months.....i was just wondering if thats what can cause this or if there are other causes...thanks

Answer 1

When u bend down to pick up a box, relax neck muscles instead of putting neck up like a turtle.
Just relax head straight down, relax neck muscles and u
will see a difference.
Bend knees also when bending.
Situps every other day is good for back.
