hi im 17 years old. for about a year i been having poop that feels like needles. my stool is either hard or super soft, there is no good in between. For a few days about 4 months ago my stool was covered in red blood. usually every time i poop there is a tiny bit of bleeding on the toilet paper that i believe is cause by scatches from the poop or something. for a couple days now i have had white mucus or something on my stool. i am scared to even go the washroom because of the pain pushing it out. im a athlete, in top shape and i eat healthy. I hear only old people usually get colon cancer. I do not know im my grandma ever had colon cancer, but she has had cancer several times, the first time she was diagnosed at 7 months. im scared of polyps. my appitite has decreased and i am tired alot and even get headaches more frequently. about two years ago i did have round worms but i got rid of them, and this is nothing like that. im starting to freak out please help.
