My father is having pains below his chest though ECG reports are normal. He has frequent gas and acidity problems though as per his general physician's advice, he does not consume milk. He has taken medicines from time to time as per doctor's advice, however the problem still persists. He is allergic to sulphur painkillers. He is physically active and does not have any age-related problems as such. Please suggest a diet or home remedies for his acidity problem.
