My initial reaction was to tell you that you don't have to worry about it because marks which appear as a result of doing energy work tend to heal quickly and go away. After reading that you see it as a good thing, perhaps it would be better to suggest that you document it somehow, by taking a picture or drawing a sketch of it. A photo, digital or otherwise, would be better than a drawing because it would be more complete. When it heals and disappears (often without leaving any evidence afterward) you might want to have the evidence in another form that it really had been there. Just in case you have doubts after the fact and for your own personal reference.
