I would definitly call your GI about
this and if he/she feels it is important for you to come in then make an appt. I know when I feel uneasy about
something and it is something I feel cant wait then I call and if you dont think it can wait until business hours tomorrow they have to have someone on call. They may ask other symptoms etc and they may feel it can wait until the morning etc
Is it bright red D or is it almost black? Bright red can mean a fissure or a hemmie and not always CD...doesnt mean it cant be but that is another option I always have D since my surgeries and my blood I get is from a hemmie
