when i defecate it is mostly undigested food i've been having flash headaches and fevers. what could it be? . i've been feeling pretty ill lately. fevers light headedness kidney stone coughing congestion blurred vision fast headaches accompanied by dizziness undigested food instead of phecies and weakness. i can't find any information on the web. maybe it's a couple different things at once.
