Carpal Tunnel Syndrome can, unfortunately, be quite common among nail professionals. It is a painful condition in the wrist where the carpel bones misalign and cause pressure on the nerve. It can start with tingling or weakness in the fingers. It can be caused by repetitive motions, such as buffing, or vibration, such as a poor quality e-file that has too much vibration in the hand piece. It can be avoided by doing frequent wrist exercises and changing your hand position when buffing. It is also best to invest in a good quality e-file if you choose to use one. It can be difficult to cure without surgery.
