What Causes Heaviness And Pain In Chest?

My wife has had her pc on her abdomen for long periods of time, she feels sob,chest heaviness not severe ,and sensory not right. It has been going on for a few days and when she puts computer on chest symptoms return,she is convinced it is due to wifi and needs to detoxify. She is not shocked or diaphoretic and is totally stable now. She gets very upset with me as I dont take the wifi theory or her seriously and that I feel that we should check out ht etc in normal fashion
