It's not particularly bothering me, I'm just a little worried that this could be a sign of something more serious.
A few days ago I noticed that the feeling in one fingertip (left ring finger) is gone. Not the whole finger tip, just the middle of the flat bit on the opposite side to the fingernail. It feels kind of like when you smack your finger on a table really hard or something and it goes numb, or when your fingers are really cold and it goes numb (but it's not cold).
I assumed it'd go away in a couple of hours but it's persisted for a few days now. Like I said, I'm not bothered about it, I just don't know if I should be concerned or not.
