I have been having back lower back pains now for over a year, i am only young so i dont understand why i have it.

I only have to be on my feet for an hour and i get pains in my lower back. it will then hurt me when i go to sit down after standing for an hour. i don't know its anything to do with me falling on my butt a bit ago, i don't know. it can be so painful, Ive been to the doctors and all they said was to do exercises but they just dont work.

For the long career im going into im on my feet 24hours so i need to get it sorted any ideas of what it might be? and how can i have it treated?
