Thank you for the query.
As you have been diagnosed with acid relfux disease, you should be also told that this disease in 80% is associated with asthma
disease. And the main symptom of asthma is severe cough. That is why you should have blow test (spirometry
) performed which will either rule it out or confirm it.
Other possible reason of severe cough can be hypertension
medicines (ACE inhibitors).
If severe cough can not be explained with any respiratory tract
disease, it is worth to check abdominal cavity as cough receptors are also located in the diaphragm. That is why, abdominal ultrasound
should be done if no findings in all previous tests.
Hope this will help.
