That’s also totally not true, believe me there are several who have, probably many more who never came back (we do get the odd person sign in after years who got better) and natural recovery is quite likely after a couple of weeks or months. Also I know of a few from Reddit and elsewhere who just got better.
Please try and stay calm, like Greek and I keep saying the chances are you’ll get better. People with PFS are hugely rare.
Relax as much as you can, don’t try and take anything to recover, just let your body do it’s thing and don’t stress.
There’s new studies coming, this website definitely isn’t the only place looking into this either. But right now you have to wait a few weeks and see. I know that’s difficult, you can DEFINITELY believe me that I know too, but please wait and stay as calm as you can friend.
EDIT - I’ve just read back, apart from the panic right now all you’ve got so far is some ED? My GP (who, again, has prescribed this to hundreds of people) hasn’t EVER seen anyone who didn’t recover from that. Ever. Until me. Just think about how likely it makes it that you’ll mend.
I know it’s a shock, I really do, but the best thing you can do right now is stay as calm as possible and ride it out. I’m sure you’ll be ok.
