Thanks for your question on Healthcare Magic.
I can understand your concern.
No, this can not be due to tb or pleurisy.
TB is not caused by this. It is caused by tubercular bacteria.
Same way pleurisy is caused by
lung infection and this can not cause lung infection.
In my opinion, he is having
allergic reaction to that liquid which is causing all the symptoms.
So better to to give him combination of anti allergic (
montelukast) and anti histamine (levocetrizine or
fexofenadine) once a day fir 7 days.
He will mostly recover with these.
He is definitely not having
tuberculosis or pleurisy.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your brother. Thanks.
