Lump in the anus with pain and itching from hemorrhoids
If you wonder why I have a small ball in my anus, you should know that hemorrhoids, also known as piles, are one of the main causes of lump formations in the anus. This condition arises when there is abnormal pressure in the rectum and anus area, generally caused by constipation problems, leading to swelling in the veins that run through this area, and may even cause bleeding.
Normally they are internal, but there are also external hemorrhoids, either because they come directly into the anus or because the internal ones, in the rectum, having more pressure every time you try to evacuate, end up descending to the outside, which is known as hemorrhoidal thrombosis external. The size of these can vary and can hurt to different degrees. If they are mild and external, you may notice a lump in the anus that comes and goes, coming out when it is evacuated and reducing when a certain time has passed and it has deflated.
The symptoms of hemorrhoids are:
- Presence of reddish blood, not dark, in the anus or on the toilet paper when wiping after having a bowel movement.
- Appearance of tender lumps near the anus.
- Annoying pains when sitting or defecating.
- Itching and stinging in the anal area.
There are several treatments to deal with this condition, such as anti-hemorrhoidal creams, pain relievers, ice or warm water packs, and laxatives to soften the stool and relieve tension. Although these techniques usually give good results, sometimes surgical intervention is necessary, but this should be recommended by a doctor who has carried out the necessary previous studies.
In oneHOWTO we give you some tips on how to prevent hemorrhoids.

Ball in the anus due to anal fissure
Another possible cause of noticing a lump in the anus is a anal fissure or a small tear. In this case, what you may notice is a small lump or lump in the anus, in or near the sphincter, pain, discomfort, stinging, itching and underwear or toilet paper slightly stained with blood. Fissures in this area occur when there is a small tear in the mucosa, which usually happens mainly when there are problems of chronic or prolonged constipation, anal sex without lubrication or trauma.
This wound that occurs when the mucosa is torn can present a small lump in two situations:
- To the fissure infected, a lump may be noticeable next to the wound and purulent discharge will come out of it.
- One time the mucosa heals, the skin is thickened. It usually presents a ball shape in the anus, especially when the scar is formed on the sphincter and, in this case, it does not have to be infected at any time. When the little ball that is noticeable is the scar, it does not have to hurt if it has already closed completely, but it may hurt a little if it is still closing.

Anorectal and perianal abscesses cause lumps in the anus
Another reason Why do lumps appear in the anus? are anorectal and perianal abscesses that are caused by a noticeable accumulation of pus in the area of the anus, specifically in the anal glands that are located on the sides of the anal canal, giving rise to the formation of a bulge in this part. The causes of these abscesses can be of infectious origin due to the entry of bacteria into a fissure or crack in the mucosa or due to the obstruction of the rectal glands, when these do not drain the fluid they produce well, which serves to lubricate the stool. , and that usually end up giving rise to a secondary infection. Between the symptoms of anorectal and perianal abscesses the following stand out:
- Pain in the area of the anus, especially when defecating.
- Formation of a lump or nodule.
- Inflammation, redness, and hardening of the affected area.
- Pus discharge from the anus.
- Fever.
- Constipation.
There are risk factors that facilitate the appearance of this problem, such as the use of diapers for a long time in infants, so it is vital to change them very often, ulcerative colitis, Crohn’s disease, diabetes, anal sex, HIV and taking some corticosteroid medications and chemotherapy.
When there is discharge of pus produced by the abscess, antibiotics and analgesics should be given, as a previous step to resorting to a surgical procedure if the doctor deems it necessary. If you want to know more about this condition, at OneHOWTO we will tell you all about the causes and treatment of perianal abscess.
Lump in the anus due to perianal or anal fistula
If you have a lump in the anus with pain and itching it can also be caused by a perineal fistula or anus, apart from the hemorrhoids already mentioned. It is a wound that is opened as an outlet for a localized infection in the rectum, the anal canal or the skin around the anus and the part of the perineum. Therefore, you will notice a lump that may be part of the abscess in this area or, if it is more internal, you will notice the lump from the wound itself, which is very inflamed. Among the main symptoms of perianal and anal fistulas we find the following:
- Lump or bump in or near the anus, which is usually hard.
- Stinging, itching and pain to the touch, rubbing of clothing, when sitting and, especially, during evacuation.
- Purulent suppuration
- Bloody discharge
- Irritation in the anus.
- Blood in the stool.
- Fever if the infection spreads.
This condition, which is the result of an abscess that has grown enough to tear the skin and create a fistula or fistula, can be caused by other conditions such as some STDs, blows or trauma to the area, Crohn’s disease, as a secondary result. from diabetes or cancer.
It is necessary for a doctor to evaluate the severity of the fistula and recommend the best treatment in each case, although it is usually necessary to deal with oral or injectable antibiotics and practice a surgery to clean the area well, removing all the pus, and if it is possible to close the fistula, something that is not always feasible.

Rectal prolapse, a lump that comes out of the anus and hurts
Another of the main causes of lumps in the anal area is what is known as rectal prolapse, which means that the rectum canal prolapses, that is, it comes out of its place and, specifically, it detaches itself, going out towards the anus and the exterior, depending on the severity of the prolapse. It is produced by constipation, diarrhea, sphincter problems, anal injuries, nerve damage that alter the control of this area, among others.
Between the rectal prolapse symptoms we find the following:
- Red lump in the anus, which protrudes from it mainly when straining to evacuate, but which can also come out when standing, walking or running.
- Problems defecating and feeling that you have not finished doing it.
- Intense pain and itching in the anal area.
- Mucus in the anus.
- Blood in the anus and stools.
- Fecal incontinence
This is a problem that can only be solved with a surgery, which the doctor will decide how and when it is better to do it, although it requires a prompt solution to prevent the problem from worsening and some secondary problems arise.
Anal lump from cancer in the anus
The last possible cause that answers your question of “why do I have a lump in my anus“It is anal cancer.

These are the main symptoms of anal cancer.
