fumes inhalion may lead to acute chemical pneumonitis
and depends on the type of chemical inhaled..but with kerosene such severe manifestation is less likely...
I advise you to go for chest Xray PA view, ECG and barium meal
meet your doctor with the above reports ....
in the mean time you can try azithromycin
500 mg and proton pump
inhibitor like omeprazole 20 mg .
