Anal pain

Anal pain (pain in the bottom) can be distressing, but it's often just the result of a minor, treatable problem.

The medical name for pain in and around the anus or rectum is proctalgia.

Common causes of anal pain

Anal fissures

An anal fissure is a small tear in the skin of the anus that can be caused by passing a large or hard poo.

Symptoms of an anal fissure include:

Anal fissures can be very painful, but many heal on their own in a few weeks.

Eating more fibre, drinking plenty of fluids and taking laxatives and over-the-counter painkillers can help.

If the pain persists, you may need special ointment that relaxes the ring of muscle around your anus.

Occasionally, you may need surgery to help the fissure heal.

Piles (haemorrhoids) 

Piles) are swollen blood vessels that are found inside or around your bottom (anus). They're often thought to be caused by straining on the toilet as a result of constipation.

In many cases, piles do not cause symptoms. If you do have symptoms, they may include:

The symptoms often pass after a few days. Eating more fibre, drinking plenty of fluids and taking laxatives and over-the-counter painkillers can help.

If the blood supply to the pile has been blocked by a clot, a simple procedure can be carried out to remove the clot under local anaesthetic (where the area is numbed).

Anal fistulas and abscesses

An anal fistula is a small tunnel that develops between the end of the bowel and the skin near the anus. It's usually caused by an infection near the anus resulting in a collection of pus (an abscess).

Symptoms of an anal fistula or abscess can include:

Your GP may prescribe antibiotics if an abscess is picked up early on. If it persists, it may need to be drained in hospital, possibly under general anaesthetic (while you're asleep).

If a fistula develops, you'll usually need surgery because they rarely heal by themselves.

When to get medical advice

Many common causes of anal pain improve with simple self-care treatments, so you do not always need to see your GP.

But it's a good idea to see your GP if:

Do not feel embarrassed to see your GP – anal pain is a common problem that they're used to seeing. Your GP can try to work out what the problem is and give you treatment advice.

They'll probably ask to see your bottom and may carry out a rectal examination (where they gently insert a gloved finger into your bottom) to check for any abnormalities.

If the cause is not immediately obvious, they may refer you to a specialist for advice and further tests.
