i have been having pain in my shins, mainly on the right one, and today I have had sharp pains going from my hip into the front of my thigh. MRI from about 9 months ago said herniation and rupture (?) at the L4-L5, L5-S1. I have also fallen on my knees a few times so I am wondering if this is pain from my knees or could it be from my back. I was looking at the dermatone chart on one of the other posts and it got me to wondering if the pain in my shins could be from my back. Any ideas??? Sue
