Dear Dr.Broadbent

I need your advice because I am really desperate. I am 16 years old and I discovered last week that I have a problem with my hands.
They are blue! but I don't feel any pain. I am very scared with this problem. Yesterday my hands were blue and I couldn't believe it! I haven't taken any pills. I don't want to leave to the street because of this problem. I am sad and I need your help as soon as possible. What should I do? Help me please!

Blue hands.
