i have just returned from visiting my 22 year old daughter, who works on a cruise ship. she has had red eye complaints for about 4 months, She wears contact lenses, and changes them regularly. She also has had about 2 months of blood in and around her stools, with white spots like mozzarella cheese. she refuses to see a ship doctor and wants to wait for 2 months before she comes home. Could this be serious?
