My son is 2 years old and has been very active and well up until two days ago. Yesterday, I noticed he wasnt eating as much and he had a tough time passing his stool - but it was squishy - his bottom hurt so much that it was red, yet it came out unusually - almost a black, and he developed a slight cough. Late last night his cough became worse - it sounded like croup cough (he came down with in TEXAS last year around this time) but we currently live in GEORGIA. It very dry in the throat but wheezy in his chest, upper lungs. Today he hasnt eaten much and has coughed a lot but he had passed some stool and I noticed its still almost blackish with mucus in it and it smells foul. I am very concerned. No fever but he has taken two doses of 5ml of childrens motrin. He only seems to want sugary foods I noticed.
