question: Recently (last few days) I have been feeling "tight in my chest"...I am getting air, I can breath, there is no wheezing. Just sometimes it feels like I need to take a deeper breath than normal to satisfy the need for air. It happens at different times of the day, lasts for different amounts of time each time. I am 41 years old, its not getting worse..or better. I am not on any medications, in relatively good health, slightly overweight. Can this be allergies or something? Thank you.
