Hi Gina, welcome to the asthma/allergy boards
Did your doc happen to say anything about
an upper respitory infection? If not and you don't have asthma, it could be allergies. Does anything hurt when you are feeling this such as your lungs or do you feel heavy in the chest? I myself don't get typical allergy symptoms, I have a lot of sinus drainage and if I don't clear it from coughing or use of meds, I end up with a weird rasp in my upper chest especially in the mornings. Have you tried an OTC called Mucinex yet?
