Age :- 69 years Issue :- Dry loud cough at random times throughout the day. Cough is for around 3-4 seconds. No specific time or trend of cough. Throughout the day she coughs for about 25-30 times. This is happening for around 5 years. She is taking telma40 for blood pressure 1-0-1. Doctors who have treated her have given medicines for cough, acidity. Last doctor advised to stop taking Amlodipine and Atenolol tablets as he said this could cause a side effect of coughing. Hence she stopped taking that tablet but still the same. Please advise.
