Sometimes when I m laying down or stretching, I feel a pop in my throat, and when I swallow, I feel a great deal of pain. It happens once every two or three weeks or so, and I only feel the pain on the right side, making me think my throat shifted to the right a little... Now I have had a slight but constant pain in that area where it hurt when I would swallow for about a week... What do you think could be happening?
