I have been experiencing pain when I take in a larger than normal breath. It feels like a restrictive pain that follows my diaphram. It started last night, on a minor scale. So I began to take larger breaths to see if it would make it worse later that night it was worse. I tried taking pain meds, and it does not take away the pain. I dont feel tierd, or dizzy, my ankles are not swollen. I do not have a bluish tinge to my complection. I had two open heart surg at age 6 and 12 for sub aortic stenosis, go for check up every two years the cardio says everything looks great, I wore a halter monitor 2 months ago the cardio said there is no change. I am 27 years old. I worry about my heart being an issue alot of the time, I really need to stop, but I cant understand why I have this pain when I breath. Could you please shed some light on the different possiblites.
