my arms are turning a greenish color.
Do you wear any jewelry or cheap clothes? My neck turns green because of my necklaces. So many people have asked why and I recently found out that if the necklace is silver but isnt made of a silver metal, the paint used to turn it silver slowly dyes your skin greenish when it gets wet (with sweat or rain and such)
I have a friend who was turning "green" last year. He went to see a doctor and was told that the green was from the fabrics in some of his clothes and blanket. This may be the reason for you but I would also go see a doctor as it could be something else.
becuase your turing into a tree-accually i have never heard of peoples arms are grenn see a doctor or you could yeah jsut see a doctor
