Anal fissures are most often considered to exist when there is pain in the anus during defecation. For the treatment of anal fissures, you should first regulate your stool to avoid dry, hard stools or repeated diarrhea, which may cause severe anal pain due to long-term stimulation of the fissure. After defecation, you should take a sitz bath with compound bitter ginseng lotion or compound cypress lotion, and then apply topical ointment with Longzhu ointment or nitroglycerin ointment, which can help to remove decay and create muscle, and stop bleeding. It can be treated with manual anal dilation, which can cure early anal fissures to a certain extent. If it is an old anal fissure, with severe anal pain and a longer period of time, in this case, you need to go to the anorectal department of the hospital as soon as possible to have the anal sphincter partially removed, and after the operation, choose red oil cream gauze and other drugs for treatment, in order to completely cure the anal fissure.
