Larry has had an awful sounding cough almost all day for the past week. It is loud and sounds like a car engine trying to start but not able to, just turning over. It is a very scary sound and I would think it would hurt him although he says it doesn’t. His doctor says his lungs are clear. I know PSP brings swallowing issues. He does drink thickened liquids now. What is the next step? Will he cough like this for a long while? How will we know if he aspirates?
