I have a lump in the outer anal area that keeps increasing and decreasing in size. Please help.

Hi,

Welcome to icliniq.com.

You can have a possibility of perianal sinus or abscess. There is a pus collection around the anus. As you have this issue for three months, the other possibility is infection with secondary abscess formation. You can have another possibility of inflammation of the bowel in the form of inflammatory bowel disease. If it is a simple infection, then the treatment is straightforward and a longer and specialized treatment can help to control the issue in later stages. For now, I suggest you do stool tests and blood tests. Kindly attach a picture of it to guide you further. Please mention whether you have any changes in bowel habits, weight loss, bleeding in stools, abdominal pain, history of smoking, alcohol, any family history of similar illness, any personal history of exposure to TB (tuberculosis) patients, and any travel history. This information will help us to diagnose your problem and then treatment can be given accordingly.
