On my middle finger on the edge of the nail a few weeks back it kind of hurt and I ignored it, thinking I just bit my nail too short or something small happened. Now a week later there's a little small green spot on the edge of my finger and it does look a tiny bit swollen. My anxiety is off the roof now and I'm expecting the worst to happen at any minute. I was working with a hammer and carrying a bunch of wood but idk of thats why. Is it infected? What could it be? Any help???
