My father's voice was cracking since a couple of days for about 15 days when we took him to the ENT Specialist. There the doctor said his left vocal chord has paralysed to some extent and he needs some vocal exercise. He also suggested xray and this is the report that we got. Do you think there's anything to be concerned about? Also to add, he recently had a massive heart attack and had a stent. Can someone please help me to understand if there's any new concern we need to worry about for the lungs?
