Anal Discomfort & Pain

Anal Discomfort & Pain: Causes, Red Flags & When to See a Specialist 

Anal discomfort and pain describe soreness, itching, burning or aching in or around the anus (the opening at the end of your bowel). This common problem may happen during bowel movements or continue afterwards. Many causes are treatable, and getting advice can help you feel comfortable again.

Anal Pain Symptoms at a Glance 

• Common causes: constipation, anal fissures, piles and irritated skin. 
• See a GP: if pain lasts more than a few days, keeps returning, or you notice bleeding or a new lump. 
• Get urgent help: for severe pain with fever, pus or black or dark red stools. It’s important to remember that heavy or continuous bleeding needs emergency care. 
• Possible investigations: examination of the area, sometimes followed by a proctoscopy, bowel camera test, blood or stool tests, or a scan, depending on your symptoms. 

Understanding Anal Discomfort and Pain: Common Signs 

Anal pain symptoms, including perianal discomfort (soreness around the anus), may include: 

• A sharp or cutting sensation during a painful bowel movement 
• Burning that continues after passing a stool 
• Itching, soreness or irritated skin around your back passage. 
• A tender lump or swelling near the anus. 
• A constant, throbbing ache that makes sitting uncomfortable. 

Other symptoms can include bright red blood on toilet paper, mucus, constipation, diarrhoea or a feeling that your bowel has not emptied completely. Pus, fever or feeling unwell may be signs of an infection, so it’s important to get medical advice without delay. 

What causes anal discomfort and pain? 

Lifestyle and dietary triggers 

Hard stools and straining can contribute to discomfort and small tears. Frequent diarrhoea, repeated wiping, scented products and scratching can also irritate delicate skin. If certain foods or drinks make itching worse, reducing those triggers may help, but avoid cutting out whole food groups without advice. 

Common Conditions 

Anal fissures: A fissure is a small tear in the lining of the anus. It typically causes sharp pain when passing a stool, followed by burning that can last for hours. There may be a small amount of bright red blood.  

Piles (haemorrhoids): Piles are swollen blood vessels inside or around the anus. They can cause itching, bleeding, soreness and lumps. Some are particularly painful, especially when swollen. 

Skin irritation and itching: An itching back passage can be linked to moisture, minor stool leakage, eczema or an infection. Threadworms may cause itching that is worse at night, particularly in children. 

Anal fissure vs piles – how do they differ? A fissure is a tear, whereas piles are swollen blood vessels. While sharp pain during and after a bowel movement is more typical of a fissure, itching and lumps are more typical of piles. Symptoms overlap, so an examination is the safest way to identify the cause. 

Less Common or Serious Conditions 

Perianal abscess 

A perianal abscess is a collection of pus near the opening of your anus. Symptoms may include pain, swelling, irritation, pus discharge, fever or feeling generally unwell. If you have severe pain with fever or shivering, you should seek urgent medical advice. 

Anal fistula 

An anal fistula is a small tunnel that develops between the bowel and the skin near the anus, often following an abscess. It can cause ongoing discharge, skin irritation and throbbing pain. Persistent symptoms should be checked, as a fistula usually needs specialist treatment. 

Inflammatory bowel disease (IBD) 

IBD can sometimes cause symptoms around the anus. Crohn’s disease, in particular, may cause pain, fissures, fistulas and swelling. 

Bowel or anal cancer 

Less commonly, anal symptoms may be linked to cancer. Persistent pain, bleeding, a new lump or ongoing changes in bowel habits should be checked by your GP. These symptoms often have other causes, but getting medical advice can help you understand what is causing them and whether further tests are needed. 

When should you see a doctor for anal discomfort and pain? 

Anal discomfort and pain often have a treatable cause. However, it’s important to seek medical advice if symptoms persist, worsen or affect your quality of life. 

Get emergency help 

It’s important to go to A&E or call 999 if bleeding from your bottom will not stop, there is a large amount of blood, or you see large clots. If you have piles and severe pain, NHS guidance also advises you to seek emergency medical care. 

Seek urgent advice today 

You should contact an urgent GP service or NHS 111 if you have severe anal pain with fever or shivering, black or dark red stools, or a painful swelling with pus or feeling unwell. You should not wait for a routine private consultation. 

Book a GP appointment 

You should see your GP if pain or itching persists, symptoms do not improve with self-care, or you notice bleeding, an unusual or growing lump, or ongoing discharge. You should also seek medical advice for persistent changes in your bowel habits or unexplained weight loss. 

Diagnosing the Cause of Anal Discomfort and Pain 

Your initial consultation 

Your clinician will ask you when the pain began, whether it happens during bowel movements, and about bleeding, lumps, discharge and changes in your stools. You should tell them about any medicines you take, treatments you have tried and any existing bowel conditions. 

They may look at the skin around your anus and suggest a gentle rectal examination with a lubricated, gloved finger. You can ask to have a chaperone present and let the clinician know if you feel anxious or sore. If the examination is too painful, your clinician can discuss other ways to assess your symptoms. 

Tests you may need 

An examination may identify a fissure or piles without further tests. Depending on the findings, investigations may include: 

• Proctoscopy – an examination used to look inside the anus and rectum. 

• Flexible sigmoidoscopy or colonoscopy – camera tests to investigate bleeding, altered bowel habits or possible bowel inflammation. 

• Blood or stool tests – selected to investigate concerns such as anaemia, inflammation or infection. 

• MRI, ultrasound or CT scan – sometimes used to assess a suspected fistula or deeper infection. 

How is anal discomfort and pain treated? 

Self-care and home remedies 

For mild symptoms without warning signs, you should aim to keep stools soft by drinking enough fluids and gradually increasing fibre. Try to avoid straining or delaying a bowel movement. A warm, shallow bath may also soothe soreness. 

You should wash gently with water, pat dry and avoid scented products or repeated rubbing. Loose cotton underwear may also help reduce irritation. A pharmacist can advise on suitable pain relief, stool-softening treatments or short-term creams. You should avoid codeine because it can worsen constipation, and you should not take ibuprofen if you have bleeding plies. 

Medical and prescription treatments 

A fissure may need a prescribed cream to support healing and medicine to soften stools. Piles may benefit from short-term symptom treatments, while persistent itching will need to be assessed by a medical professional for irritation, skin disease or infection. You should follow instructions carefully. Over-the-counter steroid creams for anal itching should not be used for more than one week without medical advice. 

Specialist treatments 

Persistent piles may be treated with a procedure called banding, where a small rubber band is placed around a pile to help it fall away, or with other specialist treatments.  

A fissure that does not heal may need an injection to relax the muscle or surgery. An abscess often requires drainage, while a fistula usually needs colorectal surgical assessment.
