I had a colonoscopy Wednesday afternoon. The doctor had to remove 5 polyps. She said something about having some swelling in the digestive tract. Since having this procedure, I have been having a lot of sharp pain on my left lower abdomen. My first couple stools had blood in them. I had figured it was were she had removed the polyps. The pain was so significant last night, it kept me awake. The pain hasn't gotten any better today. Should I be concerned about the pain?
