I am experiencing anal pain, painful bowel movements, rectal lump, blood on toilet tissue, rectal pain, anal itching, rectal swelling, rectal bleeding, constipation, bloody stool, and obstipation.

Time to see doctor: Blood in the stool, trouble pooping, a lump at the anus, or constipation are symptoms that need to be evaluated by a primary care doctor or a gastrointestinal specialist. The cause can be a hemorrhoid, an anal fissure, an infection, etc... Cancer in that area would be unlikely in one's early 30's, but can happen, even in one's late 20's. Hemorrhoids are common.
