I wanted to report some positive news after my previous post ranting about my ER visit earlier in the week. I saw my cardiologist today and even though she doesn't know a lot about CFS she was incredibly helpful and supportive. I brought her a journal article and some info about the tests I want and she read them and took them very seriously. She ordered an echocardiogram for me next week to check for diastolic dysfunction which is one of my fears from what I have been reading re: CFS. I had this test about a year ago but at that time, I did not have all the POTS symptoms, OI, and trouble breathing while standing up. She felt we needed to repeat it to see what is going on and I was really happy about this. She altered my Florinef dosage a little and is contacting another cardiologist who is more familiar with dysautonomia to consult. She agreed that the ER is not helpful unless you are having a heart attack and validated my bad experience there. So, while my symptoms are pretty much still the same, I feel hopeful that someone is taking them seriously and I will have an echocardiogram to see what is going on. Thanks again to all you guys for all your support.
