Surgery is done 2 years ago for anal fissure and then no problem of fissure. I am not a patient of constipation as I am almost vegetarian only eat fish. I never eat any type of meat, junk food and fast food and drink enough water. I go toilet two times in a day and my stool is soft. But if one day my stool becomes little hard within 365 days then anal fissure occurs. So a homeopathy doctor told that fissure is not completely heal from inside, so it is coming due to little hard stool. So I took treatment for it but still I get fissure. Now my question is how it is possible that within 2 years fissure will not heal from internally? Where other part of the body if get big wound then it heals completely within 15 to 30 days and never recur. But for little stool hard episode occasionally why fissure is recurring?
