This probally doesn't seem much like the other problems you have, but could be caused by the same thing. I know how bad that shooting pain can be. I have that too. Occationally it gets suddenly bad where my back and hips will just hurt too......My chiro tells me to lay flat on the floor and put my legs up ona chair at a 90 degre angle. This helps release the tension in the back...to make in comfortable roll a towel and place under your neck. This helps re-align the spine. Never hurts to call and ask chiro or sugestions too if you know them well enough.

Hope you are feeling better I know how much it sux when in pain.
