My father-in-law has been to the doctors, coughing and wheezing, chest pain and weight loss. The doctors have given him antibiotics and steroids today, but have ordered emergency bloods tomorrow and also referred him to the hospital for a chest x-ray. Does this sound like they are worried it’s something serious? He’s a smoker and has been losing weight for a few months. He has also been off work with chest pain around 3 weeks ago and was sent home from work again this week. Should we be very worried? Are these symptoms of something really bad? Just trying to be realistic and assess the situation for the family. Thanks.
