it could be your chair i no the chair i use to use killed my lower back so i bought a new one and i was fine.
My back hurts like hell every now and then. I know how you feel, it must be the way you sit... or something. :unsure:
i killed my back on time from riding my dirtbike.. then i got bored while at home so i went on my computer and that hurt so bad!
how did you break it? my racing buddy flew off a jump on his dirtbike and landed right on his ass and broke it he has ridden in like a year... he hates siting on anything even a little bit hard
