Hello
Your husband is having very severe cough , so much so that even ,he vomits and also tears in the eyes.
He is also complaining that there is tickling in the throat , he is right , actually this is also due to some sort of
allergy .
Such cough may be due to these possibilities , these include;
1 asthmatic allergic
bronchitis , due to some allergen there develop
bronchoconstriction , this produces cough . Dust , mite , pollen , pests ,
smoking are few predisposing factors of such cough . When such patient visit I advise them to take montelukast+ bambuterol tablet according to severity of symptoms .
Dextromethophan tablet chew will relieve ticking sensation in throat .
2 Sometimes , such sudden provoked cough may be due to some inhaled particle in airways ( in lungs ) .
3
Septic pharyngitis with allergy may be the next reason of such cough .
So deal as mentioned above and take a prescription for above mentioned drug.
However , it is very difficult to establish any diagnosis merely with these findings , so consult a physician and get his opinion.
