<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had an MRI yesterday of my lumbar. It states I have slight degenerative subcortical edema anteriorly-inferiorly at L1, L2 and L3. The marrow signal is otherwise unremarkable. It also states the conus terminates at the L1-2 and is unremarkable. There are a few small Tarlov cysts within the sacral canal. I was in a car accident 6 months ago and continue to have low back pressurepain and right foot numbness and right hip pain when standing. What does all this mean?  <response>: Hi! With history of trauma, Its possible to have secondary osteoarthritis development in low spine and edema may be causing pressure of nerve roots there...cysts are a finding with OA spine, nothing to worry...conservative treatment like lumbar sacral brace, physical therapy, anti-inflammatory medicines maybe required to abate symptoms. There are medicines to reduce edema also and back rest with physical therapy shall control the disease process. Consult a spineorthopedics doctor for it Best wishesThank you Chat Doctor.
