I've been with stage 4 adenocarcinoma for 3 years now, and recently have had a worrying new symptom: it feels as if my lungs are clogged up with bubbles. It's like breathing through a straw into treacle. It happens mostly when waking up, and I can sometimes control it by drinking water and doing exercises - not much fun at 4 o'clock in the morning. Using a fan to help breathing help as well. It's very worrying (especially when just waking up) as I feel that I'm going to run out of breath before I can control it.
Is this to be expected? And does anyone have any suggestions as to how to prevent the bubbles in the first place?
