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).
Pronation is a normal part of walking or running. When the outside edge of your heel hits the ground, it supinatesâor locksâto deal with the shockwave. Your foot then rolls in a bit and your heel moves outward. Together, these actions cause you to pronateâor unlock. Pronation helps you absorb shock and adapt to uneven surfaces. But if your foot rolls too far inward, like many people, you overpronate. Overpronation can cause problems throughout your body.
