Hey Percy,
Of course you are welcome here and your support was always warm and comforting so we are here to help you. I went through some strange health issues myself but all seems to be OK now.
Your doctor may first suspect you have pulmonary hypertension based on the results of an echocardiogram.
If it's difficult to get a clear picture of your heart and lungs with a standard echocardiogram, your doctor may recommend a transesophageal echocardiogram. In this procedure, a flexible tube containing a transducer is guided down your throat and into your esophagus using only a numbing spray in the back of your throat. From here, the transducer can get detailed images of your heart. I had two of these in one day back in September looking for a hole in my heart that was not there. :) If you have this test it is a walk in the park, just shout at me and I will support you.
There are a lot of different tests to choose from as well as treatments should you have PAH so try not to become overwhelmed and worry until the tests and dx results are final.
You have a right to worry some as this is always scary stuff but stick with us and we will be here to help you.
Gentle Hugs,
Kitt
