vibrators

[Chris]

Why was this topic called vibrators rather than vibrations ?

It's funnier...

Anyway, souds like your work that's causing the issue. I'd look into some better PPE, max working times on certain machines etc to stop/slow the damage the machines are causing to your hands.

The vibrations on the bike, unless yours is knackered or you ride on dirt tracks all the time, is so little that it wouldn't cause your condition to get worse. However getting cold hands while riding will make the symptoms of white knuckle worse for a while and your hands will take a while to recover because of the condition so get yourself some decent gloves and/or heated grips, this will help the circulation in your hands and therefore help them feel better.
