I’ve been coughing for 7 weeks (quite violently). I had whooping cough. I think I also had reflux. I’ve had two courses of antibiotics, still coughing up some yellowy phlegm. Today there was less yellow and more throth. I have a very wet cough. I can’t sleep lying down. When I move I can sometimes feel a sensation in my lungs as though they’re also moving - is that fluid moving around? I get a bit breathless when I go for a walk, also when I talk. I’ve got an oximeter but it’s hard to get an accurate reading due to cold hands, the level drops after walking and also if i try to sleep lying down. I’m taking omeprazole and am following a strict diet/ lifestyle and I think the acid reflux is controlled. My energy level is a little low. However I’m much better than I was in January, and if there is fluid, I assume it’s only a little bit. Is there anything that I can do, or my GP, if it is fluid? I want to recover and get back to work as quickly as possible. If it’s not fluid, could there be something else going on?
