I was exposed to poison ivy back in 2005 and left the US to live in Trinidad & Tobago...it recurred during the time of November - December....now am living in the Philippines and it has reappeared on the same exact spot!!! I don't know if this is a seasonal thing but I am sure I have not come into contact with the plant since 2005. What can I do to stop this rash from coming back?? It looks the same and feels the same.
