Ok I have had diarrhea and a fever for the past 4 days, also I was passing blood and a small amount of blood in my phlegm, I visited a doctor 2 days ago and she took a blood sample from me and arranged a chest x-ray and stool sample. Today she called me and told me I have raised blood (that is all she said).. I asked is this something I should be worried about? She said get the other tests done.. Now I'm sitting very worried as to why I have raised blood, I'm thinking cancer :( and so scared.. Anyone can help at all as to why this is?
