TIFU by sleeping on my arm for the last year nearly leading to me making a doc appointment for suspected nerve damage.
A few months ago I woke up to my right Index finger being frozen in it’s position, I had to physically move it with my other hand to release it I’ve never experienced anything like it(I’m 40yrs old), it felt like my knuckle was a warped hinge that was would have to work it past to open the finger all the way and it would also completely freeze up if I closed my finger completely it would just stay that way, well for weeks it would stiffen up especially after waking up, shortly after I was celebrating at my brothers wedding and overheard one of his buddies literally mentioning the same symptom in his finger before he had surgery, in my case for me anyways I narrowed it down to when I started sleeping on my stomach with my right arm underneath me, in such a way I was practically dislocating my shoulder out of its socket and causing it to go to sleep(I swear it helped me sleep better) but it was cutting off the circulation causing my whole arm to “go to sleep” which I think led to my finger issue, its what I figure, I’ve started sleeping differently and after a few weeks my finger is back to normal.
TL;DR: after sleeping for a year in a position that starved my limb of blood it nearly led to permanent nerve damage.
