When I was 10 I shut my right thumb in a volvo car door- volvo car doors were ginourmously thick . It was a mangled thumb, but recovered and although it looks different it has never caused any issues.
Now at 50 it has started to hurt when I bend it, I don't feel like I have full movement in it anymore.
I will pop to the dr at some point. I was wondering whether breaks we had as children become problematic in later life?
