Palpitation is an awareness of the abnormal beating of the heart. It may occur in people with or without heart problems. Heart palpitations when lying down is not a common occurrence and can be caused by various factors.
Flat feet occur when the normal foot arches have partially or completely collapsed. When the foot is put to the ground the inner or middle side of the foot comes down to the floor rather than remaining raised. This can cause the whole foot to roll inwards (this is called over-pronation).
Another underlying cause of significant Q Angle could also be overpronation of the foot. Normal pronation occurs when your body weight rolls fairly evenly off all your toes when walking. Overpronation occurs when the foot rolls in and your push-off is from primarily the big and second toes.
