This is kind of an embarrassing question. Most people sometime in their lifetime note that there is something unusual just outside of their anus. It sometimes grows like a pea. When they touch it, it is hard but smooth, and it hurts a little.
They are concerned about what it could be and what should they do about it. It can be a mild fissure that goes away after a few days even without treatment or may be a sign of a potentially serious condition such as a colon cancer. Is this like some kind of cancer or hemorrhoid or some infection?
A lump or swelling that is painful and appears suddenly over a day or two may be caused because of many reasons such as an injury or an infection. It may also be a hemorrhoid.
Hemorrhoids are vascular structures present in the anal canal that can be very painful. In normal condition, hemorrhoids work as cushions that help in bowel control. If you are susceptible to the risk factors for hemorrhoids, the anal lump may be due to hemorrhoids.
It's more likely to be an infection if the skin around this lump is red and warm.

And this will hopefully relieve your concern.
A clinical evaluation including a digital rectal exam can diagnose an anal lump. Some patients may require additional tests to diagnose other conditions such as:
In some cases, your doctor may also ask for an ultrasound, a CT scan, or an MRI scan.
Treatment of lumps depends on the cause and diagnosis. If it is an abscess, surgical drainage is important promptly, preferably before the abscess erupts. Anal abscesses can be drained in a doctor's office using a local anesthetic.
Large or deeper anal abscesses may require hospitalization as they are operated under anesthesia.
If the anal lumps are hemorrhoids, you will need a treatment for hemorrhoids. Read about hemorrhoids treatment.
