The expression "feels like a hair on my face but nothing there" is used to describe a sensation of something touching or crawling on the face, even though there is nothing physically present. This sensation can be caused by a variety of factors, including allergies, anxiety, and certain medical conditions.
For some people, this feeling can be a minor annoyance, while for others it can be a significant source of distress. In some cases, it may even be a symptom of a more serious underlying condition, such as a neurological disorder. If you are experiencing this sensation, it is important to see a doctor to rule out any underlying medical causes.
