I'm using mouse a lot when working. Few days ago I got pain that runs from right-side of neck to shoulder. Especially, along clavicle bone which you could see between shoulder and neck. When I do regular daily work such as washing and cooking, I don't get much pain.But, I feel severe pain when I use the mouse..I think this pain comes due to mouse use..But no one believe my thought. Has some one had such a pain while using mouse for a long time?
