Recently, I discovered that near the anus there is a hard, non-moving lump, about the size of a chopstick tip, and it feels painful to touch. The body is sometimes tired as if it has no strength, sometimes it is healthy and normal. Last year, I had blood in my stools. I went to the doctor and he said that I was constipated, so my anal fissure was bleeding. The doctor asked me if a hard lump near the anus is a sign of what disease? I would like to consult a doctor about my medical condition. I sincerely thank!
