crackling popping in my throat when I rub around Adams apple, or move my neck certain ways cracks when I squeeze my neck and even when I swallow. Hurts when I swallow, eat, cough, laugh, talk, and even sometimes when I breathe, difficulty breathing sometimes. This just started happening a couple of nights ago. I'm a male 17 very athletic work out every day. What could be wrong ? What could be the cause of all this? Please help I'm very concearned.
