Around November I was washing my hands and I noticed a dark freckle spot on the inside part of my left pinky finger. It did not hurt but it did darken to a dark brown wiThin weeks. It has been there since. It is slightly raised but is about the size of a tip of a crayon. It is a symmetric shape and does not hurt at all. When most people see it they think it is a mole or some sort of blood blister that is under the skin. It is darker than most freckles or moles on my body. Any ideas as to what this could be. Thank you.
