My teenage daughter is treated for Eosinophillic Gastroenteritis, POTS, and now AMPS with a slew of conversion symptoms including swollen, painful chest, ribs, and abdomen. Today, she began laughing normally at something you would laugh at, but then her laughter became manic, scary, and uncontrollable. She fought tears vs. laughter for about 8 minutes. Her breathing was extremely shallow and quick so I held her and helped her focus on breathing. After the experience, she was confused, and felt as though she had witnessed the episode, instead of experienced it. She is calm now, though still in pain. Should she go to the ER?
