hello mum has been suffering from chest infections that leave her unable now to cough up any mucus/phlegm. She is very chesty and it won’t clear. She really needs to to able to cough it all up but is unable to. Has anyone else had to deal with this? We asked the doctor about physio, but he says she might not be able to stand someone banging her on the chest. Does anyone have any suggestions? MUm is virtually bed bound and late stage. Thank you
