My Daughter Fixed Tacos For Her Family Last Night. While

My daughter fixed tacos for her family last night. While eating, I don't know if she got distracted of what, but she said some taco went down the wrong pipe. She believes it is in her lung. She has been coughling ever since it happened, with no relief. She is getting scared. She has a high deductible so won't go to the ER. What to do?
