OT: I read your story on your personal web page and we have some eerie similarities there. I was a solo founder for 14 years when I sold most of my company (not out of obvious necessity, I had grown tired of it somewhat and a good offer was on the table). During the last few months I had developed some tingling / pressure sensations in my fingers and legs, which I first attributed to bad posture, discs etc.
It turned out that I had a tumor growing in the spinal cavity between C2 and C4 - luckily benign, but still causing stenosis effects and eventually leading to me becoming quadriplegic unless removed. I also had severe Vitamin D and Calcium deficiency (and nothing else) and was discharged after 10 days from hospital when I had surgery. My scar is naturally very similar to yours and I have 20 Titanium screws and 6 plates implanted. My day-to-day challenges are not flexibility issues though, it's chronic pain in the hands and much worse typing skills than before surgery.
Fortunately, I found an obvious successor (the most self-motivated and responsible one, not a trained manager) in my company when I left (we had 57 employees then) and he's doing great. Good luck with your company!
The problem with Tingling sensations are that it can occur for any number of reasons, in the order of occurrence - Anxiety, Spinal issues, Issues with the nerves in the hand; unfortunately I had reasons to believe, I had all of them.
Apart from treating spinal stenosis, the tingling sensations were not treated specifically as the none of the tests isolated the reason for it. But, after spine surgery tingling sensations haven't occurred much which seems to suggest whether spinal stenosis was the reason for it.
I will link[1] the article you read just for the context of others. I haven't updated it, since then my neck movements have improved.
As you say, I'm facing severe hand numbness & pain after surgeries. Medical tests didn't help with it.
I have isolated the issue to pressure on the nerves in hands while sleeping on that side. I bought wrist splint to avoid flexing my wrists while sleeping & have generally avoided sleeping on that side; it seems to have helped. This physio therapy video[1] talks about the techniques I follow. I hope it helps you too.
I'm glad that you didn't have to close your company, you took correct steps to prevent it. I helped my developers get good offers from other companies and I have closed my company.
I have scoliosis and my one hand also sometimes falls asleep when I'm lying on my one side. Good tip on getting a wrist splint, I'll try that out, thanks.
No problem, do use tissue between the splint and the skin to ensure it doesn't bite during first few weeks (i.e. like new shoes which doesn't fit perfect).
