I don't know how many times I have to say it. I don't claim positively to know it is real.
I'm going to write it just once more so that hopefully you don't miss it this time: I don't claim to positively know that ENS is real.
Here is what I do know. Nobody on this thread has presented enough information to categorically deny that it exists. So if I see people who appear to be doing that, I'm going to call them on it.
That's not how it works. The side that makes a claim has to show that it's real. Everyone else has every right to doubt the veracity of the claim until that time. Otherwise we'd all be endlessly bogged down in pointless conversations.
Anyone can come up with a wild, fantastical idea. That doesn't mean everyone else has to waste their time trying to disprove it.
Btw, if you've made such a big todo just because you don't get that, I'll be a bit upset 'cause I've been wasting my time here.
The idea that a person's physical symptoms might have a physical cause is not wild or fantastical. By Occam's Razor it is (absent other information) the most likely explanation.
I'll give you an example. Where I come from, people believe in the Evil Eye: that if you stare at someone or something with a bad intention, if you're jealous etc, you can cause real, physical harm to that person, thing etc.
I've been accused of it a couple of times (I got scary eyes). Once a friend got a headache and then called her mom and asked her to say a special prayer people say that supposedly banishes the Evil Eye, then made a big todo about how a certain person always gave her the Evil Eye (it didn't take rocket science to figure out she was talking about me).
So, my friend obviously had an ailment, if you like: her head hurt. She felt bad, she blamed it on me. It helps that we were having an argument at the time it happened. We often had arguments. She often had headaches. She believed I was giving her the Evil Eye.
You can take the events themselves and try to reason about them. Did I give my friend the Evil Eye? Was the headache unrelated? Which happened first? What tells us they were cause-and-effect? What tells us they weren't?
Except, there is no such thing as the Evil Eye and you're basing your whole reasoning process on empty air- and convincing yourself that you're on firm ground.
The thing to ask is not "did I give my friend the Evil Eye?". The thing to ask is "is there such a thing as the Evil Eye?". Equally, you should be asking whether ENS is real in the first place. But you jump immediately in discussions of cause-and-effect, symptoms and accounts. If you're already convinced that ENS is real, those are not that important. But you have to ask yourself: why do you think it's real? Just because people say they have it? There doesn't seem to be anything else at the moment.
Like others say, I don't doubt for a moment that people suffer from - something. But I'm not convinced that it's what they say it is. I don't blame people for going mad about it, I do blame their doctors for not listening to them, but I don't blame ENS, because it sounds like the Evil Eye, or Morgellon's or whatever similar crazy thing people latch on to in their desperation.
And of course the worse thing is: by latching onto ENS (or whatever), people deprive themselves of the chance to have what ails them treated.
