“The hand-arm vibration syndrome causes changes in sensory perception which can lead to permanent numbness of fingers, muscle weakness and, in some cases, bouts of white finger. It is caused by working with vibrating tools. It would be unusual for you to develop hand-arm vibration syndrome unless you had used vibrating tools for at least ten years. If you stop working with vibrating tools it may prevent mild symptoms from getting worse”.

Symptoms may take 10 years to develop
