J&J vaccine

Hey I’m new to this subreddit. I got the Johnson and Johnson vaccine 3 years ago while it was still available unfortunately and have had Autonomic nervous system problems since. I was diagnosed with dysautonomia and have some ekd abnormalities and arythmias. I’m also recovering from another Covid infection which weirdly infected me twice in the same month(Yea I didn’t think that was possible) I got covid got better for two weeks then got it even worse two weeks later and tested positive again. I’ve tried Nattokinase that made me feel bad. The only time I can be somewhat productive or at least leave the house is when I don’t eat at all. And I wake up everyday feeling like I have a massive hangover with palpitations even though I quit drinking over a year ago. I also have almost constant shortness of breath. I know different vaccine can cause different problems but just wondered how many of you guys got the J&J vaccine or have similar symptoms from the other vaccines. I’m glad I found a sub that I can talk about this without getting downvoted and hopefully more people will find it also
