Thrombosed Hemorrhoid: Symptoms and Treatment
A thrombosed hemorrhoid is an external hemorrhoid in which a blood clot has formed. It usually appears suddenly as a hard, tender, bluish or purple lump at the edge of the anus, and it can be intensely painful, often far more so than an ordinary hemorrhoid. It isn’t usually dangerous, but the first few days can be miserable, and timing matters when it comes to treatment.
See a doctor, ideally within 72 hours, if you think you have a thrombosed hemorrhoid; that’s the window in which removing the clot tends to help most. Seek urgent care for heavy or ongoing bleeding, fever, spreading redness, pus, or pain that becomes unbearable. Never try to lance or drain a lump yourself.
Symptoms
- A sudden, hard, painful lump near the anus, often after straining, heavy lifting or a long period of sitting.
- Purple, blue or dark colour from the clot underneath the skin.
- Pain that is worst in the first 48 to 72 hours, especially when sitting or walking.
- Sometimes bleeding, if the skin over the clot breaks down.
Treatment options
| Approach | When it’s used | What to expect |
|---|---|---|
| Excision of the clot (in clinic, under local anaesthetic) | Usually within the first 72 hours, when pain is severe | Quick procedure; faster pain relief and lower chance of recurrence |
| Conservative care | After about 72 hours, or when pain is manageable | Pain eases over a week or so; the lump shrinks over two to three weeks and may leave a skin tag |
Home care while it heals
- Warm sitz baths two to three times a day.
- Oral pain relief as advised by a pharmacist or doctor.
- A cushion, and short walks rather than long periods of sitting.
- Soft stools: fiber, plenty of fluid, and a stool softener if your doctor suggests one.
- Topical numbing cream for short-term relief, if appropriate.

Could it be something else?
A perianal abscess can also cause a painful lump, usually with increasing redness, warmth and sometimes fever, and it needs prompt treatment. Sharp pain during bowel movements with a small tear points more to an anal fissure. A doctor can tell the difference in a short examination.
After it heals
Thrombosed hemorrhoids can come back, particularly if constipation and straining continue. The habits in preventing hemorrhoids from coming back are the best protection.
Frequently Asked Questions
Will a thrombosed hemorrhoid go away on its own?
Usually, yes. The body reabsorbs the clot over a couple of weeks, though pain relief is faster if it’s removed early.
Is a thrombosed hemorrhoid an emergency?
Not usually, but it’s worth seeing a doctor soon, and urgently if there’s heavy bleeding, fever or signs of infection.
Can it burst?
The skin over the clot can break down and bleed. Keep the area clean, apply gentle pressure with a clean pad, and get it checked.
