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).
Here is a list of some of the common conditions associated with over-pronation in children: 1  Achilles Pain (back of the ankle) 2  Ankle pain. 3  Arch Pain. 4  Low back pain. 5  Heel Pain. 6  Knee Pain (Runner's knee and Chondromalecia of the patella) 7  Osgood Schlatter Disease (pain below the knee) 8  Shin Splints (pain in the front of the lower leg) Over-pronation does not necessarily mean your child has flat feet. Even though children's arches may be relatively high when they lie down or sit, over-pronation may not be seen until your child is standing. A certain amount of pronation is normal.
