What this experience covers

This experience covers what sclerotherapy (injection treatment) for hemorrhoids involves — from the procedure itself through the recovery and results. It draws from many anonymised accounts.

Sclerotherapy is one of the office-based treatments for internal hemorrhoids. A sclerosing agent is injected into the hemorrhoid, causing it to shrink over the following weeks. It is less invasive than banding or surgery and is typically used for smaller, bleeding hemorrhoids that have not responded to conservative care.

The pattern

The procedure

People consistently describe sclerotherapy as quick and tolerable:

Done in an outpatient clinic — no anaesthesia typically needed
A proctoscope is inserted to visualise the hemorrhoids
The injection is given into the base of the hemorrhoid — most people describe a brief ache or pressure rather than sharp pain
The entire procedure takes a few minutes
You go home immediately afterwards

Recovery

Mild discomfort for a day or two — described as a dull ache or heaviness
Some people notice a small amount of bleeding after the procedure
Normal activities typically resumed the same day or the next day
Results develop over one to three weeks as the hemorrhoid shrinks

The results

Bleeding often improves significantly or resolves
Some people need more than one treatment session
The hemorrhoid tissue gradually shrinks
Recurrence is possible — sclerotherapy treats the symptom but does not address the underlying cause

What people wish they had known

That the procedure itself is much less daunting than expected
That it works best for smaller, bleeding internal hemorrhoids rather than large prolapsing ones
That maintaining stool management after the procedure is important for preventing recurrence
That multiple sessions may be needed for the best result

For this topic, get medical advice if you notice:

Severe or worsening pain
Heavy bleeding
Fever
Black stools

Recording how you feel is not the same as being checked. These are the signs that need a doctor’s attention.

Call 911 or go to the emergency room now if you have:

bleeding that will not stop, a lot of blood (the toilet water turns red, or you pass large clots), or any bleeding with feeling faint or dizzy
fainting, a racing heart or trouble breathing
confusion or slurred speech, extreme shivering, no urine in a day, or blotchy skin
sudden severe belly pain, or a swollen, hard belly with vomiting or not passing stool or gas
you cannot pass urine at all, or your bladder feels full and painful and you can’t empty it
redness, swelling or severe pain spreading quickly around your anus, genitals or groin, especially with a fever or feeling very ill
a fever with a painful swelling near your anus if you have diabetes or a weakened immune system (for example, from chemotherapy or transplant medicines)
black, tarry stools

Call your doctor or go to urgent care today (or the ER if you can’t be seen today) if you have:

a temperature of 100.4°F (38°C) or higher, chills, vomiting, or feeling generally unwell
pain that is getting worse over days, or severe pain that stops you sitting or sleeping
a hot, swollen or very tender lump near your anus or at the top of the crease between your buttocks, or foul-smelling discharge
trouble urinating
bleeding that is getting heavier or more frequent, or blood mixed into your stool
feeling much more tired than usual, looking pale, or getting out of breath more easily than you used to
not passing stool for several days, or new belly pain

Make an appointment with your doctor if:

you have never had these symptoms checked by a doctor or nurse — whatever your age
you have had rectal bleeding for more than 3 weeks
your bowel movements have been looser, thinner or more frequent than usual for 3 weeks or more, or you have lost weight without trying
symptoms have not settled after a week or so, or keep coming back
you notice a new lump near your anus, between your buttocks or in your belly, or an itch or discharge that does not clear
you have new leakage or trouble controlling your bowels
you are 45 or over, or have a family history of bowel cancer or inflammatory bowel disease, and any of these symptoms are new for you

If you are unsure, it is always reasonable to ask. If things feel overwhelming, call or text 988 (Suicide & Crisis Lifeline) or chat at 988lifeline.org, any time. If you don’t feel safe, call 911.
