An anal fissure is a tear or crack in the lining of the anal canal. The most common cause for this is strain or difficulty passing stools. It can happen to both men and women of all ages.
Acute fissures are early fissures which have just been there for more or less than 15 days. They can be treated easily without operation. Fissure treatment for chronic fissures which have been around for 2 months or more may require surgical intervention. They have a growth called sentinel pile and feel hard to touch.
Most common causes for anal fissures include constipation, hard stools based injury while passing, frequent bowel movements can cause the delicate anal lining to tear etc. More severe causes include inflammatory bowel diseases like Crohn’s disease, Tuberculosis etc.
If you have noticed any symptoms like pain in anal canal while passing stool, severe burning sensation at the bottom after defecation, constipation, swelling, mild or severe itching etc you may have to visit a fissure doctor immediately.
