Hi.. Thanks for the query.. It seems that you are suffering from Hemorrhoids also known as Piles and the symptoms of bump sticking out from anus along with pain and blood and pus on wiping seems to be due to it.. Hemorrhoids are inflamed and swollen veins that are formed when there is continuous irritation of the veins present in the rectum area and inflammation can lead to pain and bleeding during bowel evacuation.. Consult a Proctologist and get evaluated and a clinical evaluation and anoscopy can be done for diagnosis.. In case if piles is confirmed then you can be advised: -Application of steroid and numbing ointment.. -Sitz bath that is sitting in warm water tub especially after bowels.... -High fibre diet along with laxatives like Polyethylene glycol and stool softeners like Docusate to maintain proper bowels.. -Avoid spicy food and drink plenty of water.. -In case of no improvement with medical treatment you can be advised surgical procedures like Rubber band ligation, sclerotherapy or Hemorrhoidectomy that is surgical removal of the hemorrhoids.. Hope this helps.. Regards.
