My resting heart rate is unusually fast and even if i just walk up the stairs my heart is racing like ive just ran a mile. When i exercise i can feel my heartbeat in my chin and other strange places aswell as having red, blotchy skin all over my body, mostly my face and arms. Also, after exercise, if i open my mouth i can hear my heartbeat, its like a ticking noise. My mouth goes very very dry too. Finally ive noticed that if i lie down and place something across my chest for example a book or ipad, i can see my ipad wobble alot from my heartbeat, is any of this normal??
