Hi there, I am a 32 year old male and over the last 8 or 9 years have had this rare condition of anal discharge from my anus which could happen anytime of the day or night even while sleeping. Its no smell or colour and usually unnoticeable. I have had colonosocopy performed and revealed lactose intolerance. I have suffered from constipation from a very young age and usually the discharge happens due to my inability to empty my bowel a 100%. Drinking tea or coffee would mean a trip to the bathroom straightaway.
