What could this be?

[Calstudent2009]

I really need help. Back in February my anus started to itch and I noticed small white lumps in my stool. Now I am noticing more red chunks and some yellow ones also. I've done a fecal occult blood test which was negative as well as two stool parasite tests which were also negative. I had a colonoscopy which showed nothing significant , but during the prep a ton of those red chunks came out & my anus is still itching. Any insight??

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

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??

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?
