I am male age 58 yes. I had passed some blood with stools in the morning. May be I have piles. I had loose motions few days back. I had pain in the edge of anus because of frequent watery motions. That pain subsided after 2-3 days. But today I passed blood with the stools. Blood looked like fresh blood. Some times suddenly I wake up in the night due to pain in the lower anus. Pain gets normal by passing of air. Please advise.
