Thanks for coming to HCM
Don't worry your SGPT is normal and also heart rate normal range is 60-100.
Now regarding your chronic cough
for which you usually take nise and dexona....chronic cough can be due to allergic rhinitis
which can have concomitant asthma in 50%, eosinophilic bronchitis
, acid reflux, taking ACE inhibitor
class of antihypertensive etc....
I think you must consult a chest specialist...get a chest xray done....accordingly he may advise for spirometry....get a thyroid function test done also.
