hello.. ‘Welcome to HealthcareMagic Forum’.
dry
cough can be caused by many factors such as
bronchitis, allergic to certain substances pollution and
thyroid too..
get your self investigated for T3,T4,
TSH.. to rule out thyroid being the cause.
other than the dry cough are you experiencing any other symptoms like tiredness dry mouth and skin.. sleepiness.. over eating..
wishing you good health..
