Sometimes i feel like food is stuck in my throat after eating. the i end up throwing up and a bunch of mucus comes up. i don't have heart burn associated with it.

Fullness : Fullness in the throat is often referred to as a "globus" sensation. This might be due to post-nasal dripping, chronic tonsillitis, base of tongue tonsillitis, reflux laryngitis, or outpouching in the lining of the pharynx or esophagus called zencker's diverticulum. As evident, there is a wide range of possibilities that can result in your symptoms. Only a careful physical exam by a specialist, with possible needed tests, could fully lead to a correct diagnosis.

Esophagus: Esophageal spasm or diverticulum possible, also other things. See your doc and get worked up.
