I was in Southey Ireland last summer. While there, my whole throat shutdown, which made eating not do able. I fought, through drinking water, and eating yogurt. Now I am back stateside, and I am going through spells of severe coughing, along with my throat closing down again! I drink water, which does help, but it is a constant problem. This occurs mainly when I inject soup. Can you tell me what is causing this?
