Since last 2 years I'm suffering from anal discharge(once/twice daily). It is mild, transparent, mucous like, has an odor (not stool). Usually happens when I have had food or after exercise.  It's mild, it's not flowing kind of discharge. It remains there and does not stain my underclothes but due to this, the anal area is irritated and  itchy. Also, Due to itching around the area, I have got skin abscess (3-4 times) on buttock skin area in the past 1.5 year. There is No other symptom, no pain, no constipation. I have normal and regular bowel movements. Please tell me what to do and give me some medicines . Please. Thank you.
