Just got back from the Gran Bahia Ambar. While there I received some bites on my right wrist and lower right leg. Husband didn't get any..but I heard other guests talking about it. They look like flea bites to me and perhaps are sand fleas.. who knows. I felt nothing on me but the tiny red bumps appeared anyway. They did not itch nor enlarge while there but I'm noticing that once I got home and covering them with long pants they started itching like crazy and looking larger and redder of course as I scratched. The bites on my wrist have stayed uncovered and haven't itched once..they will soon be gone.
What seems to be working! --- washing them and then applying tea tree oil (straight stuff.. not a cream) and keeping the bites uncovered. Might be cool outside but I'm wearing capris in the house and as much as I can! It's relieving the itch and they are looking better. Just hope they go away totally soon.
