For about ten years now I have had an issue with leaky bowel and severe itching. Been tested for many things including parasites. Nothing was found. The only relief I seem to get is from allergy medications like benadryl. resently , after all the changing my washing powder and cloths more frequently, I discovered that it may be something I am eating. That is a guess. My doctor is at a loss and so am I. Has anyone else ever heard of this and what else can I try? Some times the itching is so bad it makes me crazy.
