For the past week I've felt like my throat has been closing up. While it doesn't actually interfere with my breathing, I feel like it does. Also, when I drink water during this, it only seems to make it feel worse, and I cannot feel the water itself in my throat where it's at it's tightest feeling. 

My dad suffers from acid reflux and requires a CPAP machine to breathe at night. My mom, her dad and I have all had moments where we try to swallow saliva and our throats refuses to swallow and we cannot breathe for a few moments. My mom also has very severe allergies, but my sister and I only have issues in the spring or the fall while in Germany, but not where we live. I don't know if any of these things are related, but thought they would be worth mentioning. 

Any ideas of what could be causing this feeling?
