[|Human|] Cough for a year. Been to three specialists. Nasal wash daily, no mucus discharge either from wash of blowing. Been through all the otc medicines under the advice of these specialist. Done breathing tests,x-rays, cat scans...nothing showed according to doctors. What can I do for cough?
[|AI|]  Hi thanks for contacting Chat Doctor.... Noted you have persistent cough and many tests are normal... Organic cause seems less likely.... Cough here might buy chronic irritation... Avoid smoking if you have habit.... Rule out acid reflux disease as it can lead cough. Pentoprazole taken for it.... If chest discomfort feels bronchitis or asthma ruled out by pulmonary function test... You might have allergic cough.... Try to avoid allergen that lead cough. Levocetrizine useful. Ginger, onion, garlic are good for resp tract.Finally, if its troublesome cough take Conan or dextromethorphan... Chat Doctor.
