I have read your complaints. What you have is a very common problem. Anal fissures are caused by injury to the inner wall mucosa of he anal canal by the passing hard stools during defecation. This injury causes an ulceration with infection during repeated motion every time. The solution for this is to have soft loose stools which pass without straining. This can be achieved by having a high roughage vegetarian diet, green leafy vegetables and fruits. Drink a lot of water. Local medication is just temporary and useless. In addition, the pain you are having now is due to infection and pus collecton. This could be an abscess or a fistula. This will need a smaall surgical treatment . Please consult a general surgeon for this.
