@matigo Chest infections are very common in PSP, because it affects the ability to swallow properly, so food gets into the lungs. Since he was at home when he got infected, it was probably an ordinary bug, but now he’s in hospital, who knows. Not much choice about sending him there though, because he needs intravenous antibiotics, and he’s so weak normally that any additional illness means the set up at home (my mother, helpers, hoists &c) doesn’t work.
