Thanks for your question on Health Care Magic.
I can understand your husband's situation and problem.
Right sided lower chest and upper
abdominal pain is commonly due to liver and lung pathology.
Liver pathology like Hepatitis and lung pathology like
pleural effusion, pneumonia etc cause similar kind of pain.
So better to get done chest x ray and
ultrasound examination of abdomen to rule out these causes.
He is also having
indigestion.
So start
proton pump inhibitors and prokinetic drugs.
Ask him to avoid stress and tension, hot and spicy food, large meals etc.
Ask him to quit smoking and alcohol if he is having these habits.
Don't worry, he will be alright. But first diagnose himself and than start appropriate treatment.
Hope I have solved your query.
Wishing good health to your husband. Thanks.
