I had ACDF on c5-c6 in 2022 because I had the same symptoms as you. I did not have DVT or PE but have antiphospholipid syndrome which is an autoimmune clotting issue. I go for my ACDF on c6-c7 tomorrow morning (need to be at the hospital at 5:30am). I have some permanent spinal cord compression injury due to the delayed diagnosis and treatment.

Do you know what caused your DVT and PE? What medications and supplements do you currently take?

If you are able to have your surgery in 4-6 months, that would be good. Be very careful not to fall because you can get paralyzed or have permanent spinal cord injury. They will prepare you with medication prior to and the day of surgery and your doctors will advise what medications/supplements to stop/when and which to continue leading up to your surgery.
