My old man is 82 this year. He had low fever a week ago and constantly coughed. He is now admitted to tb hospital but the doctor hasnt yet figured out the problem. He coughs now, severely and consistantly even with the help of the meds. Moreover, he’s got hiccups for days and it tires him out all night. We had scanned, x-ray, checked the heart, the lung, the blood, urine, but there is nothing wrong with those. What should I do to at least stop his hiccups?
