Lately after having sex, i try to stand up, walk around and my legs are trembling/shaking, i can still walk but its hard and i feel kinda drunk! I tried to drive the otherday and my leg was shaking when i pushed down on the accelorator and break. It only happens when i stand, or my feet are pushing on something, if im lying down and theres no pressure on them, theres no shaking? Why is this happening?
