I have had three back surgeries. Each of those surgeries removed a disk from my spine. So, I am missing my bottom three disks and it is facet joint on facet joint. I am in constant pain, but have learned to live with it pretty dang well.
When I work at Kohl's, it is a bit more painful. I am on my feet for 4 - 10 hours straight - squatting down, bending, lifting, walking and walking. I decided to try some inserts in my shoes to see if a little extra padding would help at all.
