I Am A Retired CRNA. This Pm My Mother-in-law Was

I am a retired CRNA. this pm my mother-in-law was eating a dish that had almond slivers in it and felt as if a piece had stuck in her throat. I advised her to go to the ER just to be safe. My husband and I are about an hour away and his sister took her to the hospital. CT neg she is nauseated and vomiting even after Zofran and Phenergan. Keeping her for observation rest of tonight. Seems to me that she could have irritation and swelling even if the almond was only lodged for a short time. M.D. in ER said no.
