Whatever you end up doing, don't get it fused. Total disk replacement only.
I had a rock climbing accident years ago and my C4/C5 and C5/C7 were 13mm and 8mm, respectively, pushing into my spinal cord. I actually got physical therapy and gym workouts to build the muscles around my spine to fix it. It has hard going at first but it eventually corrected. Haven't has issues in many years.
If you do decide to get surgery, one of the worlds leading total disk replacement doctors is at St Lukes Global City in Manila, of all places. I don't remember his name but you can Google total disk replacement St Lukes Global City philippines" and find articles about him. He performed the world's first double total disk replacement and was going to do a triple but I never stayed up on it to see how that went.
yes, with the Covid extension they are referring to. May 29th will be last day to apply for extension and will extend you until July 29th. Per this post. I haven't not actually confirmed it but 99.9% sure its accurate.
Just be polite and follow up again and explain your date that you are leaving and that you are getting stressed out about it. I did exactly that and they updated everything within 1 day so I could upload final documents and then they approved shortly after. Relax, 9 days is a lot.
