Hello and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. It looks to me like hemoorhoid which is located in anal canal and may protrude outside. Hemoorhoids are protrusions of veins in rectal wall and there are several stages of hemorrhodal disease and the right treatment depends on type and stage of the disease. Initially it can be treated with dietary changes by having high fibre 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 early phase this is initially treated with dietary changes by having hogh fibre diet with lot of fluids and make your stool soft. Also take fruit, vegetables, avoid chocolate, refined meat, overeating and food that causes There are supplemets such as Psilium and Detralex which may help as well.
