I have a bruise on my left middle finger I don't remember injuring it . It feels like I mashed it. Anybody have an idea what it might be?
The bruise on middle finger can be as a result of hitting on an object as this can cause an injury. This is the most reasonable explanation and you can try and remember if you hit your hand recently. If the pain is too much, you can go see a doctor.
could be while u were sleeping? if u roll around u coulda hit something.
maybe you have eczema. See a doctor.
