I'm a 32-year-old male, and two days ago, I accidentally pinched the skin on my finger between the door. It was a small part, so I didn't think much of it at the time. However, yesterday I noticed a black spot that appears to be under the skin. Could this be due to a blood clot, or could there be another reason for it?
Yes, it is smashed finger and black spot caused by blood clot. It will be absorbed with time.
