Hi - First time posting, but wanted to thank everyone for their posts.
I am newly diagnosed with a mild form of POTS, and my doctors suspect it was triggered by the Pfizer vaccine. Symptoms of tachycardia, lightheadedness, and exercise intolerance started abruptly four weeks after my second dose. In retrospect, I *might* have had some occasional symptoms in previous years (slow HR recovery after extremely strenuous exercise, lightheadedness after large meals, increasing intolerance of alcohol) but nothing dramatic or notable.
I did a full cardiac and pulmonary workup (which was all normal) and the tilt table test which showed dysautonomia tendencies. My PCP says that every week now, she is seeing previously healthy people with these symptoms and she thinks anecdotally it is the vaccine, and similar to what people are experiencing with Long COVID.
I have gotten about 50% better with massive lifestyle modifications (which you all are familiar with), am rebuilding my exercise tolerance and following some of the Long COVID protocols, like breathing exercises, which seems to be helping.
Just wanted to weigh in with my vaccine experience. I have asked my doctor about taking or avoiding boosters, and she said, "let's discuss in the fall."
