I went to the ER because I thought I was having a heart attack or stroke...periodic chest pain, breathlessness after climbing a flight of stairs, a never before experienced dizzy spell, fatigue, and feeling like death warmed over. They did the whole battery of tests to check my vitals, heart, neck arteries, brain, etc. Fortunately, those things were ok. The chest x-ray showed that the left hemisphere of my lung was elevated, so they called in a thoracic specialist/surgeon. He scheduled more tests, including a Sniff test, which confirmed the paralyzed left diaphragm. The main reason I've decided to have the plication surgery in the spring to flatten my floating left diaphragm is to keep my other organs that are moving up into my lung cavity and impacting my breathing in place. The x-rays showed my stomach is in a peculiar position, which the thoracic specialist/surgeon said could be causing my periodic chest pain...something to do with changes in pressure in my chest cavity. Mayo Clinic radiologist's reports from chest x-rays going back 20 years all mentioned an elevated left hemisphere; but it never bothered me. Something must have happened in the past few months to upset the status quo and cause my shortness of breath after minimal exertion, etc. This is something new and worrying. Anyway, as I mentioned before, I'm really relieved to have a diagnosis and feel as though I am in good hands. I was glad to read you think your doctor knows what she is doing and hope you will find another one you like and trust to replace the one who moved. One of the worst parts about moving from SE MN to SW PA was leaving my wonderful Mayo Clinic doctor of 20 years and the great care I received there. Take care! Nancy
