My mother has been suffering from unknown disease. 1. While she takes a nap anytime, her heart start to pump up and body sensations starts. Sometime it does happen when she is awake as well(less heart pump compared to nap case). The problem disappear after sometime automatically. 2. Half head pain anytime 3. Sometime while moving neck cracking some appear. 4. Irritation happens when someone makes loud sound or house is closed
