Hi, It looks to me like hemorrhoid which is located in the anal canal and may protrude outside. Hemorrhoids are protrusions of veins in the rectal wall and there are several stages of the hemorrhodal disease and the right treatment depends on type and stage of the disease. Initially, it can be treated with dietary changes by having a high fiber diet with lot of fluids and make your stool soft. There are few procedures which can be used but surgery should be avoided unless there is no improvement on conservative measures. In the early phase, this is initially treated with dietary changes by having high fiber diet with a lot of fluids and make your stool soft. Also take fruit, vegetables, avoid chocolate, refined meat, overeating and food that causes There are supplements such as Psilium and Detralex which may help as well. Also, you should use sitz baths and have hemorrhoidal cream such as Procten ointment. Also, you should use sitz baths by sitting in warm water for 20minutes daily. Second, it can be treated with rubber ligation or sclerotisation and in severe stages and this can be done in ambulatory settings. On the other hand, open the surgery is recommended only in resistant cases but for this, you should consult proctologist about these options. Other causes include abscess and anal polyps but for this differentiation, you should do the proctological examination. Till that, try to follow my recommendations and see if this will be helpful. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Ivan R. Rommstein, General Surgeon
