Dear Blue,
I am also alot older. This is quite serious. Drs. can help, the sooner the better. It's suppose to be a closed (no blood) digestive system. Blood means there is a tear (you have seen evidence of this), & perhaps internal bleeding (life threathening), the Drs. can locate this area, treat it & you will heal. Please see a Dr. We care so much for you.
Much Love,
Holmes
