Hello, I can understand your problem. Fissures are very painful. They are due to tear of anal mucosa and skin which happens due to tight anal sphincter tone and straining at stools. You might have also developed infection around that. Various medical treatments are available for the same like nitroglycerin ointment for muscle relaxation, lignocain for pain relief and antibiotics if there is infection. Patient also needs lubricant laxatives, stool softener and high fiber diet to prevent constipation. Surgery can also be done if it does heal by these treatment. I advise you should consult a surgeon for further management. Hope this will be helpful. Thanks for your question. Take care.
