Not sure if it's the right place to ask but was wondering if it's normal to feel vibration sensation on thighs, the skin to be exact(not the muscle? lol i have no idea how to explain) when you're sprinting on treadmill? It does not hurt but it's kinda like "itchy", really really itchy and it's quite disturbing

Also, my entire body gets shaky after a workout? Is it good or bad?
