Hi Doc,
I'm a 24 years old adult male living in Los Angeles. About a week ago on Sunday I started to feel really tired along with headaches and some mild diarrhea and it lasted roughly 2 days, then on Tuesday I developed various cold symptoms including cough, sneezing, congestion, running nose, and further head aches. This lasted until Friday and then I started having worse diarrhea (5-8 runs a day), Nausea, along with exhaustion but less of the other symptoms. Finally today I still feel really tired and I had a brief period (1 hour) of heavy coughing and I noticed that a few times I had coughed up some blood mixed with mucus (small amounts). Then I still have the irregular bowl movements and now the stool is black in color (but i don't know if its because of the Pepto Bismo or blood, there does seem to be red traces floating around the stool). Right now my cough is gone and with minor running nose and better feeling in my abdomen, but i'm still feeling tired and a bit nauseated and I'm not sure if its just a flu/stomach flu or something else. I had the H1N1 vaccine last October, and during this whole ordeal I did not have a Fever. Please help, thanks!
