There was an increase in kids with back problems when the backpack became a popular way of carrying heavy study books to and from school.
When I went to echool, we rarely were assigned more than 1 book to do homework from per day.
When my kids went to school, they were often expected to carry 4 or 5 heavy books every day!
Both of my able-bodied daughters complain of back problems now as adults.
Another common reason for women to have back problems is if they have children and carry them on predominately one hip. Tis better to switch up and give each hip the same amount of work.
Its all about symmetry!

I suggest a long soak in a warm bath with Epson salts to soak away some of the aches and pains.
