You've noticed an uncomfortable lump outside your anus. It hurts, sometimes a lot. The immediate question is: will it go away, and how long will it take?
External hemorrhoid or thrombosed hemorrhoid: the distinction that changes everything
Technically, external hemorrhoids are a normal part of our anatomy. What people experience as an "external hemorrhoid" almost always corresponds to a thrombosis: a blood clot that has formed in an external hemorrhoidal vein, creating a tense, painful, sometimes bluish swelling.
This clarification changes the expected duration.
How long does it actually last?
The progression follows a fairly predictable pattern when left to heal naturally. The edema surrounding the clot reabsorbs within three to four days. This is when the pain most noticeably decreases. The clot itself disappears more slowly: two to six weeks depending on its size.
Complete spontaneous healing of an external thrombosed hemorrhoid therefore takes between two and six weeks. If the edema is significant, or if the clot is large, it tends to be at the higher end of this range.
Some people then retain a skin tag, a small fold of skin at the site of the thrombosis. This is not an active hemorrhoid, just a skin remnant that does not disappear on its own.
With medical treatment
Anti-inflammatories and venotonics reduce edema and alleviate pain more quickly. The most painful phase can pass in three to five days instead of a week. However, the clot still takes several weeks to fully reabsorb.
If the thrombosis is still recent, less than 48 to 72 hours, and very painful, a doctor may suggest an incision or excision under local anesthetic during a consultation. Relief is almost immediate. The small wound heals in three to six days, which is much shorter than waiting for natural reabsorption.
What affects the duration
The size of the clot is the main factor. A small, not very painful thrombosis can resolve in ten days. A large thrombosis with extensive edema can last for over a month. How you manage your bowel movements during this period also matters: each straining effort during defecation mechanically worsens the situation.
An adapted diet during the flare-up, including fiber, water, and mild laxatives if necessary, helps get through this period without aggravating the inflammation with each bowel movement.
A recurring external hemorrhoid is a sign that the venous tissue has never fully regained its tone. Sérenia addresses this mechanism where traditional creams only treat the surface.

A thrombosed hemorrhoid that heals is no guarantee that the problem is resolved. The venous tissue remains fragile. Recurrences often occur in the following months, sometimes more intensely than the first time. The underlying causes, such as a sedentary lifestyle, a low-fiber diet, and chronic constipation, continue to play a role.
This is where the difference lies between treating a flare-up and treating hemorrhoidal disease.
