I've been feeling a bit breathless for a few days and had slight chest pain. Went to the doctors today and Dr heard a crackle of fluid on one of my lungs. She doesn't know what it is as I have no other symptoms, no cough, not been ill, etc. She's done full bloods but has anyone else had this? Usually you'd expect to at least have a cough.
My oxygen, blood pressure and pulse were all fine.
