Hi, I'm really worried, 1 day go I bleeded during vowel movement, It was hard, my anus itches sometimes for 3 days or so now, & I just went the bathroom and had a really bad pain in my stomach almost made me cry, when I started to poo it wasn't hard or too soft but when I cleaned myself I saw the blood in the toilet and it was alot of blood, happened 30 minutes or so after I ate shrimp and chili...what can it be?
