<s>[INST] hi I just found out that I have hemorrhoids but that one had busted open I was given medicine for the hemorrhoid but as of yesterday I have found pieces of a black looking tar in my stool.. and just about a half an hour ago I was bleeding and still had those pieces of black looking tar in stool. should I be scared? [/INST] you should consult doctor and need to investigate. because in hemorrhoid the fresh blood is seen in the stool which is of red colour. black looking blood is seen in upper GIT bleeding. so you may have bleeding from somewhere elese also. so investigate properly and take treatment accordingly.thanks for using health care magic. </s>
