Your friend needs to seek medical advice from his health care professional. Please encourage him to do this NOW. There is no way a bulletin board advice could possibly help and many ways it could harm.
Sorry Ginger Sue - even though you state you just want ideas, this is not something we in cyber-land can provide. Please have your friend follow up with their provider. Good luck.

someone I know, but haven't seen for a while has sent email describing having a lingering cold, and now has noticed himself turning purple?
any ideas about why this might be?
