<s>[INST] Hi, i am having anal fissure problem for more than 2 years.I have tried allopathy,homeopathy and ayurvedic medicines.No use.Before ten days i got swell near my anal opening and i can realise tat and getting pain.What is the reason for swell and how to overcome ? [/INST] 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 the 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.  Chat Doctor. Local medication is just temporary and useless. In addition, the pain you are having now is due to infection and pus collection. This could be an abscess or a fistula. This will need a small surgical treatment. Please consult a general surgeon for this. </s>
