I currently have painful bowel movements. After I do, I notice blood on toilet paper (sometimes bright red and sometimes darker in color). Once time I had a bowel movement and it was nothing but blood. It's painful to wipe and even painful to spray water on while I shower. I have seen two pieces of skin that are hanging from the sides of my anus. Right not even the area in between the anus and my genitals are sore. I was recently taking amoxicillin and doxycycline for my recent tooth removal and malaria prevention (respectively), if those may give any insights on what the situation may be. I am worried because I was diagnosed with HPV a few years ago. I had warts and I had them removed. They have yet to reappear. My fear is that I may have developed anal cancer.
