YES, I had a similar experience. I accidentally found out that I was Dxed with LV diastolic dysfunction when I asked for a report of my echo. No one thought to tell me either 🙁 I came to an enlightening realization about this presentation that I want to share in hopes that it will help others.
At the time I presented with LVDD; I was having a reaction to a beta blocker that I had recently been prescribed for severe Reynaud’s. I should have known better, BB’s and I don’t get along well. My allergic reaction presented with a numbness in my chin, that progressed up my face and into my mouth. Once my lips, and throat began tingling and going numb; I finally realized I was having an allergic reaction. I stopped the BB and had the echo redone a few weeks later- PERFECTLY normal!!! In my case, the LVDD was the manifestation of stirred up mast cells.
BTW, I am DXed with MCAS, POTS, NMH, and an unknown connective tissue disorder (most likely EDS III.)
