I have most of what you have. I have a clotting issue but mine is more risk for clotting than risk for not clotting.

A diameter of 5mm is suffocating your spinal cord of blood flow and oxygen and spinal fluid. An average person has a diameter of 13-15mm. Yours is extremely compressed with is a cervical myelopathy spinal cord injury. You can become paralyzed if you fall so it is a priority to get surgery to stop the further damage to your spinal cord. This compression damage can become permanent.

I had ACDF surgery on c5-c6 and soon to have ACDF surgery on c6-c7. I have a herniated disc at c6-c7 that is making my already congenitally narrow spinal canal only 8mm.

You should ask your surgeon if your cervical MRI shows that you have a congenitally narrow spinal canal (believe this would be anything 10mm or less which is what I have). I started having problems in my 40s and I am now in my 50s. People with congenital stenosis have more issues with degenerative changes earlier than others (many don’t have issues until they are in their 60s).
