..what is it and is it normal?
I was doing some DIY flat pack stuff and slipped and ended up slicing my thumb quite deep. It bled for quite a while but stopped eventually and has started to seal together again quite well.
My thumb hurts and is sore as expected and the bit of my hand under my thumb is sore too.
A bit further up my hand there is a small pale bluish bumb. Not big. It is directly on/over a vien which is also bluish tinged. It hurts when pressed, quite a bit.
What is it?
