I get what looks like a scratch on my lower leg. I was in Mexico, working at the Embassy, when I first noticed this and the Embassy doctor called it a spontaneous eruption and prescribed, I believe fragil, or close to that. Said it would get rid of something or other that was in my system. I don t recall what he said it was but I think he called it a parasite, again not sure other then it would get rid of whatever it was I have seen this several times over the past year, 2017, and it goes away after a week or more, then comes back at a later time. Now in the area where the scratches have been coming up I get the feeling like the skin is being stretched and now I m finding those scratches on the other leg. Can you suggest something?
