Hello! I have been through your question. According your concern you shouldn t be worry because I think this is a sign of hemorrhoids. Usually this could happened when you eat something spicy and have constipation. Hemorrhoids cause pain, severe itching, and difficulty sitting, blood on your tissue after having a bowel movement as you had. Fortunately, they are treatable. Although hemorrhoids are painful, they aren’t life-threatening and often go away on their own without treatment. What I suggest for you to prevent or avoid worsening hemorrhoids is , avoid straining during a bowel movement also, try to increase your water intake, drinking enough water can keep your stool from hardening and if you’re constipated use some fiber supplements. . I hope my answer help you. I wish a quick recovery.
