Boils and carbuncles
A boil (furuncle) is a pus-filled bump in the skin that is caused by a bacterial infection. It is a bit like a very big yellow pimple, but it’s deeper in the skin. Medical treatment is often helpful. It can make boils go away quicker, relieve the pain and prevent complications.
Pneumonia
Pneumonia often leads to a sudden high fever, the feeling that you are very unwell, a cough and shortness of breath. People who are otherwise in good health generally recover from pneumonia within a few weeks. Children and older people might not have the typical symptoms, which can sometimes make it difficult to diagnose.
