I also have developed some kind of heart issue. Im on metoprolol. My heart rate is always above 100 the cyst can cause POTS. I have no clue if the cyst is a side effect from the vaccine or not like I said it wasn't there in 2015.... i have no clue if im still leaking from the lumbar puncture i have no clue anymore my life is constant worry and regret. I truly hate my life... i feel drunk all the time light-headed dizzy confused can concentrate very forgetful severely fatigued my legs swell terribly... i dont feel there will be a back to normal for me.
