Anal fissures are considered to be painful during bowel movements. Anal fissures are formed when the skin of the anal canal is broken due to dry stools and straining during defecation. Fresh anal fissures do not take long to develop, usually only a few days, so you can take oral laxative drugs such as lactulose oral solution and marijuana capsule to soften the stool and promote the discharge of stool to avoid secondary stimulation of the fissure, and insert diclofenac suppositories in the anus to relieve pain and apply local hemorrhoid cream or anal ointment to promote the healing of the wound, usually about 10 days of medication. The fissure can heal on its own within 10 days. If the onset of old anal fissures is usually longer, more than half a year, the fissures are already fibrotic, the use of drugs is not obvious therapeutic significance, it is necessary to operate, after the operation requires regular daily drug changes, the wound healing time of about 20 days.
