See a doctor: Palpitations and dizziness that disappear with sitting or lying down are not suggestive of an acute heart attack, but these symptoms need evaluation. The numbness and burning of the left arm may or may not be related. There are many possibilities for these symptoms, including panic disorder, episodic irregular heart beats, anemia. Please see your doctor for examination and appropriate tests.
