A year ago I was drinking alot of sodas and eating alot of junk such as candy cookies and chips, a large large amount. Then a few months into my bad diet, I started seeing blood in my stool. I stopped eating what I was and started on a healty diet. Since then my problem has eventually stopped. Sometimes I'll forget and drink a cup of soda but then the next time I use the bathroom theres blood. I also can't eat nuts anymore without them causing extreme discomfort. I used to eat almonds without any pain but now eating even one almond could cause as much discomfort as pain in my chest (like an irritation). Why? Can anyone help?
