Your MRI shows you have cervical myelopathy spinal cord compression injury. This is most likely behind many of your symptoms. I am a 55 year old female with cervical myelopathy/osteophytes/degenerative disc disease/stenosis and I had ACDF surgery on c5-c6 and now need it on c6-c7 due to a new herniated disc. Cervical myelopathy causes many issues below the level of compression but can also cause headaches and brain fog due to compressing blood vessels to brain. You need to see an orthopedic spine specialist/surgeon asap because you need to stop the progression of the injury and permanent damage to your spinal cord.
