IANADoctor (and neither are most people likely to view the image). I think the only blister that well defined that i've ever seen in the flesh was from fat hotter than boiling water. Also, for me, it suggests something i doubt, namely that its visible diameter is greater than the diameter of its intersection with unblistered skin, i.e. that the skin has stretched not only perpendicular to the surrounding unblistered skin, but also parallel so that the boundary from that less disturbed skin is hidden in this view; likewise, that if the film's plane were perpendicular to this photo's film plane, the shape might be more like a mushroom cloud or a center-supported water tower than most blisters. If that's the case, it should be clearer, and if not, it's likely to be misleading for others as well.
IMO, a side view, or better yet, side and top views of the same blister at the same time would be far more effective.
