Sometimes we have health problems that are a little difficult to talk about, but very painful. A red, swollen, painful lump near the anus is one such thing. The pain when sitting, walking, or going to the toilet can be so annoying that you can't even do your daily activities. Have you had such an experience? Then don't be afraid of this condition. Let's talk about it in detail and simply.
What exactly is an anal abscess?
Simply put, an anal abscess is a painful, pus-filled lump that forms under the skin around your anus or rectum. There are small glands inside your anus that help retain moisture. When these glands become blocked for any reason, a bacterial infection can develop and pus can build up inside them. That pus builds up, forming a painful lump.
The most common type of abscess is called a perianal abscess, which forms near the opening of the anus. It usually appears as a red, tender lump. Sometimes, abscesses can also form inside the anus, in the rectum. They are not visible.
The relationship between anal fissure and fistula
Another thing you should definitely know about when talking about this is what is called a fistula. Many people (about 50%) who develop an anal fistula will later develop a fistula.
A fistula is an abnormal tunnel that forms from the site of a pus-filled abscess (inside the anus) to the surface of the skin. This is a way for the body to release pus that has accumulated due to an infection.
This fissure can cause frequent pus, sometimes with a little stool or blood, to come out of a small hole in the skin. Sometimes, if this hole closes, pus can collect again and form a new abscess. So if you have frequent anal fissures, there is a good chance that the cause is a fissure.
What are the causes and risk factors for the development of these tumors?
There is no single cause for an anal fissure. There are various causes and risk factors that can contribute to this. Let's look at them in a table.
| Cause/Risk factor | A simple explanation |
|---|---|
| Blocked anal glands | This is the main and most common cause. Bacterial infection inside the glands causes pus to accumulate. |
| Anal Fissures | Bacteria can enter through small cracks in the rectum due to factors such as constipation and cause infections. |
| Diseases of the digestive system | People with inflammatory bowel diseases (IBD) such as Crohn's disease or ulcerative colitis are at increased risk. |
| Diabetes | People with diabetes are at high risk of developing any infection. |
| Weakened immunity | People with weakened immune systems due to conditions such as cancer medications (chemotherapy), steroid medications (prednisone), or HIV are also at higher risk. |
| Other reasons | Sexually transmitted diseases, anal injuries, smoking, and chronic constipation can also contribute. |
Is this hemorrhoids? Or an anal fissure? Let's know the difference.
Many people confuse this condition with hemorrhoids. This confusion is reasonable because both occur in the same area and both cause pain and itching. However, these are two completely different medical conditions.
Hemorrhoids are not an infection. They are swollen veins in the anus. An anal fissure is a pus-filled abscess caused by a bacterial infection.
Let's further clarify this difference with the table below.
| Characteristic | Anal Abscess | Hemorrhoids |
|---|---|---|
| Nature | A lump that is pus-filled, red, swollen, and feels warm to the touch. | A swollen blood vessel that looks like a purple-blue, solid lump. |
| Pain | Constant, sharp, stabbing pain, especially when sitting. | You may feel pain, itching, or discomfort, but it's not always severe. |
| Fever and chills | Yes , this is an infection that can cause fever, chills, and shivering. | No , hemorrhoids are not an infection, so they do not cause fever. |
| Pus discharge | If the abscess bursts, pus may ooze out. | There is no pus. There may be a little blood. |
How does a doctor diagnose this?
If you have these symptoms, it's important to see a doctor . The doctor will usually ask you about your symptoms and examine the area.
- Physical examination: The doctor will look at the rectum and the surrounding area, checking for swelling, redness, and pain.
- Digital Rectal Exam: A gloved finger is inserted into the rectum to check for lumps or other abnormalities.
- Other tests: Sometimes, especially if the tumor is internal, a scan such as an ultrasound, CT scan, or MRI may be ordered to confirm the diagnosis. A colonoscopy may also be recommended to rule out other conditions, such as IBD.
How is it treated? Will this get better on its own?
The most important thing to remember here is that an anal fissure does not usually heal on its own. It definitely requires medical treatment.
Warning: Do not, under any circumstances, attempt to remove the pus from this boil at home or prick it with a sharp object. This can worsen the infection and lead to life-threatening complications such as sepsis.
Surgical Drainage
Often the best and only treatment for an anal fissure is to perform a minor surgery to completely remove the pus.
- Small external cysts: These can usually be done in the doctor's office (OPD) in a few minutes under local anesthesia.
- Internal or large tumors: In this case, you will need to be admitted to a hospital, anesthetized, and have this surgery performed in an operating room under general anesthesia.
After surgery, the incision is usually left open until the pus has completely drained. It is not stitched.
Recovery time after surgery
The pain after surgery is greatly reduced. To help you recover quickly, your doctor may recommend the following:
- Painkillers: Medication will be given to control the pain.
- Antibiotics: Antibiotics may be prescribed to control infection, especially if you have other conditions like diabetes. It is important to take these medications for the full duration.
- Sitz Bath: This is very important. Sitting in a basin of lukewarm water for 10-15 minutes several times a day can reduce pain, keep the wound clean, and help it heal faster.
- Preventing constipation: Taking laxatives ( laxatives ) and eating fiber-rich foods (fruits, vegetables) can help reduce discomfort while going to the bathroom until the wound heals.
Complications that may occur if proper treatment is not taken
If this is ignored as a minor matter, serious complications can occur.
- Fistula formation: As we discussed earlier, if a tumor develops, there is a high chance of a fistula forming.
- Spread of infection: The infection can enter the bloodstream and spread throughout the body, causing a dangerous condition called sepsis.
- Frequent cyst formation: If the pus is not properly removed or if an abscess develops, these cysts can continue to form.
- Fournier's gangrene: This is a very rare but life-threatening infection that causes rapid death of the tissue around the genitals.
Therefore, the best thing to do is to seek medical advice as soon as symptoms appear.
Take-Home Message
- An anal abscess is a painful, pus-filled lump that forms around the anus.
- This should not be confused with hemorrhoids. Fever and severe pain can be symptoms of an anal fissure.
- This condition usually does not heal on its own, so if you have symptoms, don't waste time and see a doctor.
- Avoid trying to squeeze or pop the cyst at home. It can be very dangerous.
- Often, the treatment involves a minor surgical procedure to remove the pus. This is a successful and safe treatment.
- If you have frequent cysts, talk to your doctor about that as well, as there may be a fistula hidden underneath.
