I have had difficulty swallowing for about two months. I feel like i have to put force into swallowing food. Also, once it goes down, it feels like the food gets stuck in my throat and chest. The more i eat, the tighter my throat feels. Besides this, I also have constant chest pain, abdominal pain (like solar plexus to groin where it hurts when any pressure is applied), and nausea. I also burp a lot and regurgitate acidy liquid.
