I injured my finger the other day, there is a cut, it is numb and also slightly bruised.
It is painful but not overly so. But the thing I'm not sure about is the circled area. It is a slightly raised bump, that makes my finger feel odd when I touch it (I don't know how to explain it).
I will go to the pharmacy on Monday and ask the pharmacist to take a look, but not much I can do till then.
