22 yrs old male 5'3 130 Ib this morning I woke up fine three hours later I get a really painful stomachach with sweat and chills. I could not poop, but tried really hard after half an hour, diahrea came out. Still having the painful stomachache, I go to the bathroom again,but nothing, except for som kind of red liquid. I was constipated since yesterday. Is there any serious problem I'm having?
