Im 24yo I have had 2 kids. The last year my lower back has been popping out. The first time I was doing some excersizes at home. then it was fine for months then I bent over a few month ago and it snapped hard. since that recent one it has constantly been a problem. frequently any bending over or carrying my child makes something pop out and then its quite painful for days and anymore bending whatsoever makes it worse.
