I am just intrigued to know if anyone else has experienced this. Feeling quite well today I decided to use a cordless strimmer to tidy up a little overgrown area in the garden, the strimmer is very light so I thought I would be OK, after 15 mins my hands were aching so I stopped but my god the vibration has completely exacerbated tremor to such an extreme it's ridiculous and in both hands normally only right hand it's quite scary, just typing this has took forever
