Hi.
Thanks for your query.
There looks to be a serious problem as per your history.
The sudden onset of pain in abdomen- sweat and chills- unable to poop in the beginning , followed by diarrhea- pain continues and now red liwuid...
This is very classical finding of a disease called ''intussusception''.
In this condition the part of the intestine enters into the intestine to give a tube-in-tube  appearance. 
You need to rush to ER.
Do not take anything orally.
You have to go for :
X-ray of the abdomen in the standing position and-
Barium enema- as for diagnosis and many times it is the treatment on its own. The pressure of the barium can resolve the intussusception.
Once the problem is sorted out temporarily, you have to undergo definite diagnosis by way of 
CT scan , 
colonoscopy and other investigation and the treatment then is well planned to remove the cause that caused this. 
At the same time this helps to rule out any other pathology.
