Mum has what I think is pleurisy and has been this way since she was about 45, (she's erm.. 5...6ish lol ) every now and again she gets pains in her lungs and can't breathe and it feels like they're filling with water, which lasts for a few weeks and fades away... she always has a horrendous 'morning' cough that sounds like an animal dying as well, every morning since I remember... she smoked a lot until she was 50... do you think she might have something seriously wrong? She refuses to see a doctor due to complete insanity... her mum died a few years ago of undiagnosed lung cancer because she refused to see a doc too, in fact everyone in that side of the family that can be remembered has died of lung cancer...
