question: My heart beat is inside my head and then it pauses with a funny little bump or flutter in the middle of my chest. I can feel the little flutter/bump in my chest especially at night when I am at rest. I also have heartburn. Recently, I feel off of a small three step, step stool while hanging curtains and landed flat on my back. Could the fall have done something with my heartbeat? I did go to the emergency room with two small fractures on my spine.
