I had a facial injury when I was 16 that ripped many nerves. I’m 41 now for context.
My lower left lip was totally numb for months. It felt like dead leather at first. As it started healing, everything I barely could feel felt like I was touching another area, and very tingly at that.
Over time, I’ve gradually regained most of the feeling in my lip, I’d say like 85% or so, and it no longer feels weird like it originally did. When I touch my lip, now I can tell exactly where I’m touching it, albeit a little numb.
So I guess that in the 25 years since it happened, apparently my nerves have healed about as much as they ever will, and my brain has apparently adapted accordingly.
