Tony seems to be suffering from a cold, sore throat. Problem is he is making the most horrendous noise trying to clear his throat or cough. This went on for 5 hours yesterday and has started again an hour ago. He was given oromorph last night and eventually settled but seems to be building up again. He has been suctioned but doesn't make much difference, its so tiring for him. Has anyone else experienced this, its also so hard to understand why he can make so much noise but cant speak.
