My friend got a severe nose bleed last night. He was drinking heavily but there wasn't any trauma to his face, it just started bleeding. He does have cold symptoms right now. My question comes from helping him clean up his bathroom. The blood was pink. Dark pink but certainly pink. It was the color that made me worry something might be wrong. He says he gets nose bleeds sometimes and I shouldn't worry. But the color was so unusual I want to make sure.
