Stretching your tight forearms can feel fantastic - you just need to follow a few simple steps.
Often we forget that the muscles of the fingers start in the forearm and that simple tasks like holding your finger up above the mouse button - can actually tighten up the forearm. Then there are things like gripping the steering wheel for long periods, typing, holding your massive iphone or ipad in one hand all day etc - they all create tension in the forearm that can lead to soreness and other problems.
So try this easy stretch and see how it feels for you.
Hope that this has been able to give you some pain relief.
