Information for Patients


An abscess is a pocket of pus. You can get an abscess almost anywhere in your body. When an area of your body becomes infected, your body's immune system tries to fight the infection. White blood cells go to the infected area, collect within the damaged tissue, and cause inflammation. During this process, pus forms. Pus is a mixture of living and dead white blood cells, germs, and dead tissue.

Bacteria, viruses, parasites and swallowed objects can all lead to abscesses. Skin abscesses are easy to detect. They are red, raised and painful. Abscesses inside your body may not be obvious and can damage organs, including the brain, lungs and others. Treatments include drainage and antibiotics.

Tonsils and Adenoids

Your tonsils and adenoids are part of your lymphatic system. Your tonsils are in the back of your throat. Your adenoids are higher up, behind your nose. Both help protect you from infection by trapping germs coming in through your mouth and nose.

Sometimes your tonsils and adenoids become infected. Tonsillitis makes your tonsils sore and swollen and causes a sore throat. Enlarged adenoids can be sore, make it hard to breathe and cause ear problems.

The first treatment for infected tonsils and adenoids is antibiotics. If you have frequent infections or trouble breathing, you may need surgery. Surgery to remove the tonsils is tonsillectomy. Surgery to remove adenoids is adenoidectomy.
