I've been noticing a weird sound coming from my lungs every time I breathe. It's really thin, and sometimes I have a cough too. Whenever I work hard, I get short of breath. I haven't had any chest pain or noticed any blood, but the sound in my breath and the shortness of breath are concerning. What do you think might be going on?

It sounds like you may be experiencing mild respiratory issues, such as wheezing or reactive airways, which can cause shortness of breath and a dry cough, especially with physical exertion. I recommend seeing a doctor to assess your lung function and rule out conditions like asthma or other respiratory concerns.
