Two days ago felt my throat was burning nothing special begin of a flu I thought. Same night i could not sleep because had a running nose but could not blow my nose, mucus kept in my body. Swollowed it trough while laying in bed. Next day when I woke up I felt extremely tired and had headache, but I figured thats normal because was not able to sleep the night before. Stayed home all day and went to bed not to late. During the course of the night I woke up with havy stomach spasms and when I went to the toilet I noticed that my stool was liquid maroon coloured blood. The stomach pain continued all night long and each time I had to walk to the toilet for temporary relief. I also need to mention that while walking from the toilet i fainted a couple of times..Do you think I should go to the emergency? and what would be your first reflection after my description above.
