Everything hurting for no discernable reason isn't normal at your age. The difference between your 20s and 30s is that in your 20s you don't need to do anything to not hurt. In your 30s and beyond you're gonna need to start taking care of yourself in order to not hurt. The pain is your body telling you something is wrong. Could be sleep apnea, hypertension, lack of activity or not enough recovery after activity. Again though, pain all the time for no reason isn't actually normal until much later in life.
