Mom just turned 93, is healthy except her Anti depressant and stool softener and other Bowel issues. But this has happened twice now where she is eating and I don't know if it went down the wrong "tube", or what, but she coughs and coughs for about 15 minutes. Im wondering if this is something to worry about? She eats regular foods with the family, just nothing spicy. She doesn't always want to walk out to the kitchen, and both times this happened she was sitting in bed. I wonder if her position has anything to do with this?
