Been Getting Sick while Eating

So lately I've been feeling sick in the  throat when I eat. I'm not sexually active so I'm not pregnant buuuut I do want to know if this has happened to anyone else before. 
I may know why I'm feeling this way, cause my throat is smaller than normal cause of swelling from allergic reaction's in the past and (small) asthma attacks. Or something of the nature. But that only affected me swallowing food. It never really connected to me being sick while eating. 
I don't throw up when eating but I get that uncomfortable feeling like I'm about to.
I don't know. has anyone been through something like this? Can I get some advice?
