I have a popping sound when i swollow its going on 2 weeks i also get a tightness feeling in my throat...also have a feeling of having something stuck?

Reflux: Most likely reflux. Along with taking a ppi (prilosec otc - take 1 hours before meal). You should try do the following. Keep your portions small. Do not eat 2 hours before you lay down. Try and sleep on an incline (you can do this by sleeping on a wedge pillow). Avoid these foods: acidic foods (tomoto's, onions, red sauce) fatty foods, chocolate, mint, and of course spicy foods. See ur md if not.

Diagnosis: I feel you need to go and get evaluated as i'm not sure if you mean your throat is popping or your jaw joints as both need to be evaluated.
