Hi I went to the doctor about 3 months ago for shortness of breath. She did a chest xray which was normal, ecg normal, blood pressure high. She said the shortness of breath was due to anxiety. She put me on meds for that and blood pressure. Well still 3 months later I still have the shortness of breath. With no exerise, I can just be sitting down, does that still sound like anxiety. I asked her about lung cancer cause I used to smoke for 13 years. I am now 29. She said no it would of showed up in the xray and blood work. Does anyone know if this true?
