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).
Having Flat Feet (Pes Planus) or Fallen Arches can lead to following medical condition: 1  Nerve impingement or entrapment of calcaneus. 2  Plantar fasciitis. 3  Tarsal tunnel syndrome. 4  Posterior tibial tendinopathy or tendinitis. 5  In rare cases, weakness in the lower extremity muscles can be felt.
