And sometimes my toes hurt. would this maybe be the effect of my spinal injury?

Very Likely: If your spinal injury was between the leveis of l3-s-2, particularly l-4, l-5, and s-1, then your toes may very well be percieved as painful. In fact it is due to damage along the "telephone lines" between your toes and your brain. The wires which carry messages from your toes to your brain may be "scratched" at the level of your spinal chord. This could feel like pain in your toes.

Could be: Nerves to the feet and toes start out in the spine.
