Hi and welcome to Healthcare Magic. Thanks for your question...
It is likely that your throat problem / pharyngitis
could have been precipitated by the inhalation of the pungent fumes.
The pain in the 'epigastic' region and the gas could be indicative of gastric irritation, which may be a side effect of the antibiotic medication or the pain-killers (both of which can cause gastric irritation and hyperacidity
). You can try taking some antacids or cold
milk and see if there is an improvement. Avoid taking more pain-killers. If there is no relief or if your pain is worsening, then you should report this to your doctor.
Wish you all the best.
