I've had episodes of blocked nasal passages and choking, as early as this summer, but have been experiencing swelling of the lips and tongue for about a month. I feel pressure and fluttering sensations under my ribs. I have anxiety, and my heart races. My fingers and toes had started to become blue and numb, at one point. It's difficult for food to move through my lower esophagus, but these feelings are reduced when I expectorate fluid.
