I've not eaten any fruit or drank much recently and i have constipation that feels like i'm trying to squeeze a brick out for last 5 days and its has no blood but the stool its self is a bit darker than normal i'm very worried?

Constipation: This situation, often called being "impacted," is a symptom more than the real issue. Please see your doctor or go to your emergency room. You may be dehydrated and even malnourished, which will create other issues. Once your colon empties you need to follow up w/a health care provider for guidance to avoid this in the future and rule out any medical conditions. Hope you feel better soon.
