Ive been noticing a thin sound when I breathe, almost like somethings coming from my lungs. Sometimes I have a cough and when I exert myself or work hard, I get short of breath. I dont have any chest pain or blood, but this sound and the shortness of breath are worrying me. What could it be?

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.
