im 14 years old and when i would be doing anything, standing, sitting or even laying down, my lower back feels pressured and i always feel the need to BEND it. sometimes it would hurt but thats very rare. ive felt it for quite awhile.. a few years i think, and to me it seems to be getting even more pressured as time passes. im thinking of making an appointment to go to the doctor, but i was just wondering what i MIGHT be having, and if its anything to worry about?
