Hi, thanks for the query to H. C. M.
Inhalation , if any foreign body in lungs it will produce cough uninterrupted (bout of cough)
If you have cough from this incident than inhalation of some plastic material could be imagine.
If such type of symptoms are there than you have to consult a physician and he will get a
bronchoscopy of your's lung to find out any foreign particles in airways( pharynx, trachea,
bronchus .
If cough is not there than it might be a mistaken thing.
Your's question is this that there are burning in throat and also irritation, these two symptoms are same things just to fear of inhalation of a foreign thing.
2 nd reason may be some injury due to engulf of some thing in
esophagus to stomach.
Take an
antacid with oxycetacain ( local
anesthetic) at the advice of doctor whichwll give immediate relief.
Please get one X ray of abdomen to find out any plastic like thing in stomach (color X ray)
Regards.
Dr. HET
