What do MRI results mean if they say mild reversal of the cervical lordosis with early dehydration and annular bulging at C4-5?

Sorry that your answer hasn't been replied to yet, and I don't know everything about what you are asking but, I know about the lordosis. "Mild" reversal of the cervical lordosis is way better than a complete reversal. The Lordosis is the actual curve in the cervical spine (neck). Normally, the lordosis curves inward toward your throat. If there are changes in the lordosis, it means that it is starting to straighten (first) out to what they call "military neck". I have a complete reversal of the lordosis which means that my cervical spine has lost the complete curve and actually curves the opposite way. This is due to a whiplash injury from a rear-end collision in July of this year. I also have bulging in the same area as you, and problems in T1, T2 & T3. Bulging of the C4-5 is where your cervical vertabre is bulging out of your spine. More than likely due to disk injury. Each vertabre is numbered. There are 7 vertabre in the neck area, each are numbered starting from the joint where they spine and head connect. (Cervical 4 & Cervical 5) The term cervical deals only with the neck. Thoracic deals with the upper back. So, after C7, it then changes to T1, T2 etc. Good luck on your recovery. It's a long road or so I hear to finally get back to normal or close to it!
