Hello, Don't laugh at me please... I'm a scalper, I Stay 9 hours a day in front of my computer with my right hand on the mouse ready to click... I guess I'm not the only one. Since 6 months, my right arm, pectoral, shoulder and shoulder blade are starting to hurt. In fact not really hurting, they are just really stiff, especially at the end of the week. At one time I was afraid it was my lung, so I got to the doctor. I reviewed my symptoms but didn't give me some solution, other than "painkillers". Is it common or is it just me because I have too much tension? Does someone knows a good remedy? I thought about starting to trade with keyboard but my methods don't allow it, especially with the platform I have now. Thanks a lot for your help.
