I recently had an MRI done because my back kept snapping when I walked. I found out that there were changes from my last MRI 4 years ago. I now have bulging dics in D11 & D12. Along with CSF cysts that are abou 4 mm each. I'm waiting to get my appt to see a neurosurgeon. My doctor sent my records, I just haven't heard from the neurosurgeon. Can someone give me some advice on what this means? I'm afraid to do any exercise as I don't want to hurt my back any further. I ended up missing work because of all of this because my back kept going out.
