Hello all, i had pleurisy twice many years ago and the first time was a awful experience for me and the story doesn't matter but the answer does!! a Doctor simply said to me... there is nothing i can give you for it as far as drugs, go home and lay on your back on the floor in front of the sofa, put your feet on the sofa up to your knees and stay there for about 30 min to an hour and do that twice a day. :/ well i thought ummm are you serious? i can't breathe!! lol well i had no other option ...
