Throat feels like sand inside and makes me feel like throwing up.3 days. no other symptoms. i have chronic allergic rhinitis also?

Throat: Your symptoms may be related to allergies so you would benefit from a physical examination by a board certified otolaryngologist

Let's see: If your nose is mostly obstructed from allergies, your mouth may feel dry from mouth-breathing. Heavy post-nasal drips may also contribute to the irritation and remotely possibly the nausea as well. If the problem is that severe,you should consider seeing an allergist .
