Red chunks, and yellow chunks sound like something you could be eatting. The white stuff could be mucas.
I use hemorrhoidal cream everyday for my itching. I use it in the morning, and nite, and it really helps.I just put it on the outside. I get itching from my Irritable bowel. Using Tuks after you wipe helps to. Sometimes not getting really clean can cause itching.
What does you Doctor say about all this?
My dr said it could be worms but I've had multiple tests to rule that out. I've even been given a full round of blood course-work, all which came out normal. I don't believe I have hemorhoids either, wouldn't that be noticed during a colonoscopy??
Yes a colonoscopy would see hemorroids. I itch, and I don't have worms, or anything like that. It could be the soap your using, or anything like that. If your doctors scratching his head not knowing what to tell you....then get a second opinion, and try the tuks, and hem cream
