I have this pain in my lower back down to my feet. When im sitting or lying down im mostly fine. when i walk, it tingles slightly, however if i stand still, my feet feel pressured and the the pain builds up right till my lower back,if i move the ain disspates, as i keeep standing still the pain returns. if i stand and bear it a little longer, my elbow muscles begin to ache, it s like blood is flowing down and collecting in my leg or something, i cannot explain.
