I have been having bowel problems for more than 6 months. My symptoms include: stomach bloating, constipation, sometimes diarrhea, lumps on anus, anal bleeding, pain in the area and severe itching. My doctor has not done an exam and simply put me on Bentyl. He has done a CBC and after asking for a colonoscopy or exam he told me that my symptoms do not warrant one. I am at my wits end and need advice on what my next step should be. Thank you.
