What will happen to me?

Most anal tears get better with simple treatments. But if you have a chronic tear (one that has lasted for more than four weeks), you may need a small operation to help the tear heal properly.

About 8 in 10 people with an anal tear get better with simple treatments such as taking warm baths and changing their diet. This usually happens in about three weeks.

Some people need other treatments such as
 
 
 
 
 
laxative
A laxative is a kind of medicine you can buy over the counter. Laxatives empty your bowels by making you go to the bathroom often.
 
 
 
 
 
laxatives or ointments to relieve their pain.

Chronic tears are less likely to heal with simple treatments. Most people who have chronic tears need treatments to help relax the muscle that controls their
 
 
 
 
 
anus
The anus, which is at the end of the rectum, is where a stool leaves your body when you go to the bathroom. Part of the anus is a muscle that helps you hold in the stool until you are on the toilet.
 
 
 
 
 
anus. When this muscle relaxes, the blood flow to the skin of your anus improves. This helps the tear to heal.

Treatments to help the anal muscle relax include:

  • A small operation
  • Ointments that you rub into your anus
  • Injections.
Surgery works for about 9 in 10 of those people who need it.

It's unusual to have more than one tear at a time, or for the skin on the sides of your anus to tear. If this happens, your doctor may do some tests to see if the tears are due to an
 
 
 
 
 
infection
You get an infection when viruses, bacteria, fungi or other tiny organisms get into your body. These bugs are so tiny that you can't see them without a microscope. For example, an infection in your airways causes the common cold. And an infection in your skin can cause rashes such as athlete's foot.
 
 
 
 
 
infection or a problem with your digestion.
