Truth is, I had this a lot in 2011 after walking very fast and then having to teach. I felt very breathless. Even just going up a flight of stairs. I thought it was because of the PTSD, post flashbacks, my body felt "different."
Now, I think that I get "flares" of this that are progressively increased levels.
Comparing notes with my only sister who also has PTSD (same dad/abuse) and she also has the same breathlessness, but notices it most lying down in bed on her side. Same for me. We get heart pounding and arrhytmias if we don't move and lie flat after that breathlessness, tight chest sets in.
My tests say Lupus/Sharp's. Sharp's symptoms fit. Pulmonary Hypertension in severe symptoms is Sharp's (Mixed Connective Tissue Disease).
So it's not "new" for us or our family or me, but it's "worse."
So I'm hearing, only with panic attacks, not just daily life. Okay. Thank you because that confirms that I need to keep pursuing my medical diagnosis with these symptoms. They are nothing to ignore like I have before.
Cheers, and glad to have an EMT and those with personal experiences to share.
