You can’t dash potatoes after anal fissure. There is no cure for anal fissure after smearing potatoes, and there is no scientific basis, according to the patient’s disease condition, targeted treatment. And on the anal fissure wound wipe potato, but also easy to cause infection. For acute or incipient anal fissure patients generally use non-surgical treatment methods, including general treatment (such as sitz baths, regular defecation), drug treatment (such as nitroglycerin ointment, nifedipine ointment, etc.). Surgery is often used for patients with recurrent fissures who are not well treated with conservative therapy. If diagnosed with anal fissure, it is recommended to go to the anorectal department of regular hospitals as soon as possible for standardized treatment to reduce the adverse effects of the disease. Do not believe in the so-called partial prescriptions, secret prescriptions, special effect formula.
