May I ask why you suspect this is a parasite? I have had these types of "scars"randomly showing up for a year now. Some are actually in the shape of triangles or circles as well. They started on my face and have now spread to the rest of my body. I have seen them show up right before my eyes in the matter of minutes and they do not go away. I have been doing a parasite cleanse for 4 months now and am removing some worms but I do not feel that these scars are/were a direct result of parasites eating my skin. I am just curious as to what makes you believe that this is parasite related...I am still trying to get to the bottom of why this is happening to me as well
