Axar.az reports citing Yahoo Style that they are a key way for many people nowadays to capture a special moment - and probably post it on Instagram later.

The action of taking a picture of yourself - with or without others - using a smartphone, risks the development of a painful nerve condition.

An increase in what has been branded “selfie wrist” corresponds with a growing obsession for people to share images of themselves on social media.

“The wrist holding the camera phone is in a flexed position: that is the most unfavorable position,” explained Dr. Raj Ragoowansi, a consultant plastic surgeon based on Harley Street, who has seen a spike in patients complaining of the injury.

“The carpal tunnel is an unforgiving space in the wrist - if you keep on taking selfies, the blood supply of the nerve in it will be compromised, causing pain and numbness.”

It is triggered because people have to perform a repeated inward flexing of the wrist to get a flattering angle.
