Few months ago i went through really dry bowel movements and it caused me to have fissures. i noticed the outside of closing anul muscle isn't firm enough to close but it feels loose. is there a cure for this situation as it is effecting my life?

The fissures could heal if you allow a different environment to allow healing, like: increase healthy oil in your diet to serve has lubrication for ease of passage of bowel movement, increase fiber and water in your diet and learn healthy nutrition that promotes regular bowel activities. I do not know your symptoms; and it takes time to heal and maintanance is more important as a way of life.
