The other day i accidentally swallowed a big chunk of a burger i felt light headed and vomitted after that i felt better didnt feel light headed but since then i've been feeling pressure on my throat and i find it hard to eat full meals just now today i was drinking some soda and it got hard to breath and i vomitted again (I rarely ever vomit last time was over 3 years ago today and that incident the other day was the first times i've done it in a long while. 

 

I was wondering if this could be something i should see a doctor over or if its just something that will pass. 

 

The pressure on my throat is on the upper left side
