I have a tendency of anal fissures occurring if my stool becomes little hard and I have very weak digestive system so suddenly my stool becomes little hard and anal fissures occur though I follow this diet chart- high fiber diet, drink lots of water, green vegetables and fruit, I do not eat oily and spicy food, avoid fast food and junk food but still suddenly my stool becomes little hard and anal fissure occur and for this problem 1 year ago surgery also done. So when my stool will be hard then if I insert my finger in anus and then pull hard stool then this technique will help to prevent anal fissures or it aggravate the chance of getting anal fissure? Pls tell in details, I always in fear about anal fissure though I try my best to keep this disease under control.
