A month or so ago I fell and cut my elbow, I cleaned it and stuck it back together with steri strips (probably needed glue or a few stitches but oh well). Anyway today my sister pointed ot the scar and said it "looks wrong". She thinks there is some gravel or something in there and it's infected. I think possibly it a keloid scar. It's very very sensitive and hurts if I touch or knock it so I don't want to go poking and prodding if it's nothing. So what do you think, stick a pin in it or leave it alone?
