### Patient: Doctor, I have been experiencing a disturbance of my sense of smell or taste. Can you tell me what's wrong with me?
### Doctor: You may be suffering from a decubitus ulcer, which is also known as a pressure ulcer or bed sore. These ulcers are caused by prolonged pressure on a particular area of the body, such as when lying in bed or sitting in a wheelchair for long periods of time. In severe cases, they can lead to tissue death and a loss of sensation in the affected area, including the sense of smell or taste.
