Hi, I started with breathing problems on Friday night and continued to be breathless all weekend. It was like an asthma attack but felt different. I have asthma and I know it was not an attack as I ve had them before and been hospitalized and the last time was approx 4/5 years ago. My breathless has settled but I now have a different symptom. I feel like there is something there but can t cough up, it s as if the muscus I should bring up is stuck inside my lung. My cough sounds do different also. I m not coughing all the time but as a smoker I always bring up at least a tiny amount which is very normal for me but that s not happening even though I can here/feel a small rattle now and again. I also have a cold feeling in my lungs when I m breathing. Hope this makes sense. I m a nurse but this might not come across as educated but there s no other way to explain it. Help
