Hello I need advice.
I have this injury on my arm, the cut is quite deep, and it touches the fat layer.
It's been a week and a half and it still hasn't cicatrized at all. The gap of the wound mesures one centimeter and it bled for more than 24 hours. The injury is totally black, dry and a weird grey liquid pours out of it.
Is this necrosis ? Should i seek medical help ? Thanks in advance.
