Since the advent of the internet, people have been able to discuss their symptoms with others globally. Sometimes people with very unusual symptoms discover others with similar experiences, which they are then able to discuss without fear of ridicule. Discussion forums and support groups are formed and eventually a new medical condition may be recognised. A case in point is “visual snow”, which individuals experience as bright dots persistently floating like snow across their vision. Another is trypophobia.
