since the heart is the pump that supplies oxygen from your lungs and since you are getting out of breath with minor exertion seeing a cardiologist is a good next step. you may need an exercise treadmill test with attached to an electrocardiogram oxygen sensor and ultrasound. i don't think this important evaluation to rule out a heart-related cause would be a waste of money.
how can i find a doctor for a specific breathing issue? . if i walk up stairs or cardio exercise i am out of breath immediately my heart pounds and my legs feel tight. i have been seeing multiple doctors to no avail. i've been told: acid reflux asthma and vocal cord dysfunction. i've seen doctors for and treated all 3 and guess what - i still can't breathe. . how do i find a doctor to treat this? i have asked to be sent to a cardiologist -- but i don't think i should be doing all the guessing here and throwing my money away. thank you.
