2. Worrying about spinal pain‘Well, I’m afraid I can’t do the same things as other children, and then I can’t play with them. It is also really difficult to bicycle home and everything…’#1:55b152
3. Pain intensity‘…It just stops like, I almost can’t breathe …’#5:55b280
4. Difficulties to define the pain*‘… One night, I was just about to go to bed, my mom asked if I was feeling alright, I told her that my back really hurt.

Personal factors
