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).
Foot, Hip and Knee Pain Foot, knee and hip pain can be the result of biomechanical foot imbalance. Excessive pronation (feet rolling in too far, very low arched feet on weightbearing) or excessive supination (feet rolling out, very high arch on weightbearing) creates poor foot and leg alignment when walking, creating an unstable and inefficient base of support for your body.
