I have been suffering from anal disorder for the past one month. This problem had happened in the earlier too almost 2/3 times in the past. I feel bitter pain when I pass my stool, but sometime, not each time. I feel bitter burning on the around surface of the anal and lower ass. Now, three days ago, skin disorder(swelling) created and showed in the surface of lower ass, which is so much painful. How can I treat it and can get complete relief ?
