What is the Difference Between Anal Fissure and Abscess?

There are plenty of differences between the two conditions.

Anal fissures and abscesses should never be confused for being identical. Spots are localized pus pockets generally brought on by bacterial infection. Abscess can occur in any part of the body. Abscesses can develop as the bacteria sink into the tissues in the anal canal.

Who Can Get Abscesses

Those with conditions that weaken the body’s immune system, such as cancer or HIV/AIDS, are more likely to get anal abscesses. It is important to note that spots can cause tenderness, swelling, and pain in the affected area. Patients have also complained of fevers, chills, and weakness or fatigue. Most symptoms clear once the abscess has been drained.

What is an Anal Fissure?

On the other hand, a fistula or fissure is a small tract created when inflammation is present in the body. In some cases, however, fistulas can develop due to an infection. They are not always associated with abscesses. However, some diseases, such as Chron’s Disease, make it more likely for fissures to develop.

Unlike abscesses that develop in the area that has been affected, fistulas can develop elsewhere in the body. For instance, if a woman is suffering from obstetric injuries, fistulas can start opening up on the bladder and vagina, not necessarily in the anal region. Like abscesses, fistulas must be drained. However, they don’t cause as much pain and only have the risk of irritating the skin.

Why is There Confusion About the Two?

Abscesses and fistulas can occur together. If a fistula opening heals before it is cured, a spot can grow behind it. You will need to go to a doctor who will examine the affected area to get diagnosed. When the abscess or fistula is near the anus it will be excruciating and cause swelling and redness, which can be relieved through home remedies.

To be diagnosed, the physician will need to look for openings in the skin and discern how deep they are and the direction of the fistula. If a fistula or abscess is absent on the skin’s surface, the physician may have to do more research.

They may need to utilize an anoscope to look inside the anal canal and lower rectum to see if they can detect something. A method for draining or removing the fistula or abscess will be determined from there.

As you can see, the differences are minimal. However, it would be best never to try and self-diagnose yourself when dealing with fistulas or abscesses. It is always better that the moment you realize something is going wrong that you reach out to a medical professional for advice.

Trying to treat yourself could cause a risk of infection or other complications.

Could you talk with your doctor about treatment options and remedies to prevent either from happening in the future?
