Hello, I'm 19 years old and about a month now im experiencing constipation and rectal bleeding.. There is no blood in the stool but sometimes i saw a bright red blood in the toilet paper.. The blood is only few but i remember the time that after i finished my session in the toilet and was walking to work my a** just feels itchy and when i got into work i wipe it and its bright red blood... The bleeding is not always there it comes and go and it was like i have an irritated a** after a bowel movement.. And after i increased my fiber and water intake my stool become soft, but something new bothered me.. i saw a black tiny dot in my stool.. but few, maybe only three dots? I want to know of what is happening to me.. Im so scared.. Looking forward to your answer's..
