I saw a Pulmonologist today who did PFT's that were normal. I had a normal chest X Ray and a normal EKG this morning.
I have to go for a right heart catherization next Wednesday (a day after my 26th birthday - just great!) to rule out Pulmonary Hypertension. My breathlessness isn't coming from that because even if I do have it, it's too mild to cause these symptoms.
I am seriously at the end of my rope with this. I have a constant feeling of breathlessness and tightness in the chest. Not so bad while sitting, but definitely worse with any exertion. The worst part is, I have no idea what is causing it or what to do for it.
