SYMPTOMS & CONCERNS

Anal Lump or Swelling

An anal lump or swelling may be caused by a thrombosed external hemorrhoid, prolapsed hemorrhoid, perianal abscess, anal skin tag, or another anorectal condition.

The size, tenderness, timing, colour, and whether the lump is associated with pain, bleeding, discharge, or bowel movements can help identify the likely cause.

At AC Hemorrhoids & Anorectal Centre in Calgary, we provide assessment and diagnosis of anal lumps or swelling and discuss treatment options based on the clinical findings.

⚠️ Sudden Painful Lump or Rapidly Increasing Swelling?

A sudden tender lump may be caused by a thrombosed external hemorrhoid, while painful swelling with fever, discharge, or worsening tenderness may suggest an abscess or infection.

What Does the Lump or Swelling Feel Like?

Different patterns may suggest different causes.

Common patterns include:

  • Sudden painful or firm lump
  • Soft or painless skin-like lump
  • Swelling that appears during bowel movements
  • Lump associated with bleeding or prolapse
  • ender swelling with discharge or pressure

When to seek assessment:

  • The lump is painful
  • Swelling is increasing
  • Bleeding or discharge is present
  • The cause is unclear

Could It Be a Thrombosed External Hemorrhoid?

A thrombosed external hemorrhoid can cause sudden pain and swelling near the anal opening.

Common patterns include:

  • Sudden onset of pain
  • Firm, tender, bluish lump
  • Symptoms may be most intense during the first few days
  • develops after heavy lifting, straining, or increased abdominal pressure

When treatment may be considered:

  • Pain is significant
  • Signs of infection after lancing or drainage
  • The lump remains painful or continues to worsen after drainage
  • Conservative measures are not enough

Could It Be an Abscess, Skin Tag, or Prolapsed Hemorrhoid?

Not every anal lump is a thrombosed hemorrhoid.

Other possibilities include:

  • Perianal abscess — painful swelling, tenderness, fever, or discharge
  • Anal skin tag — soft skin-like tissue, often painless
  • Prolapsed hemorrhoid — tissue that comes out during bowel movements
  • External hemorrhoid — swelling or tissue around the anal opening
  • Other anorectal lesions — may require examination to identify

Urgent/Emergency care:

  • Seek urgent or emergency care if symptoms are severe, rapidly worsening, or you feel faint, very unwell, or have heavy bleeding

How Is an Anal Lump or Swelling Assessed?

We aim to provide accurate, respectful, and private assessment. Your visit may include:

  • Review of when the lump first appeared
  • Discussion of pain, bleeding, discharge, and bowel habits
  • Comprehensive anorectal assessment, which may include perianal inspection, digital rectal examination(DRE), and anoscopy
  • Ultrasound or MRI may be recommended if an abscess, fistula, or other deeper anorectal condition is suspected
  • Referral back to your family physician or to another specialist may be recommended if findings suggest a condition that requires further investigation

Frequently Asked Questions

What causes a painful lump near the anus?

A painful lump may be caused by a thrombosed external hemorrhoid, perianal abscess, swollen hemorrhoid, or another local anorectal condition.

A firm or hard tender lump may occur with a thrombosed external hemorrhoid. Other causes are possible, so persistent or unclear lumps should be assessed.

Yes. External hemorrhoids, thrombosed hemorrhoids, and prolapsed internal hemorrhoids may all feel like a lump or swelling around the anus.

A hemorrhoid may cause a tender lump, bleeding, or prolapse. An abscess is more likely to cause constant or worsening pain, swelling, tenderness, fever, or discharge.

Seek prompt medical care if the swelling is rapidly worsening or associated with severe pain, fever, significant discharge, heavy bleeding, or feeling very unwell.

Not Sure What the Lump or Swelling Is?

Different anorectal conditions can look or feel similar. A focused assessment can help determine whether the lump is related to a thrombosed hemorrhoid, prolapsed hemorrhoid, skin tag, abscess, or another condition and identify the appropriate treatment.
