so sometimes when i bend my back in an arch,not all the time just some,even with no weight,i get a sharp pain in my spine like un the
middle...it doesn't hurt to bad but it makes me jerk to straighten my back

any ideas?
Just call me Julius, J, etc.
Taking an Internet break for a while, will come on when I can.
A doctor? Chiropractor? Not an internet forum full of people under 18 who don't know the first thing about spinal injuries or ails?
