Hi Gwen and Welcome to NeuroTalk. Sorry about your spine probs, but glad you found us. Sorry, I'm not good at diciphering my own Xrays/MRI's, so couldn't begin to offer up any suggestions to you. Have you seen the Dr since having the tests for their opinion?
But, I do have a grinding on my L5-S1 due to bone on bone. My Xrays and MRI confirmed it. Hope you take a further look around and please make yourself at home.
