I'm happy to debate this reasonably with anyone.....
FND, is in my opinion, incredibly damaging and even dangerous a diagnosis to be given. From all I have read and witnessed, it is a waste basket diagnosis that encapsulates too much to be of merit. There's a word salad type plethora of, well, word salad, on the website FND Hope. No hope for me there on reading I'm afraid.
Why are the FND departments all within psychology wings of each location across the country? That makes me uncomfortable.
I've watched a video from one of the guys who birthed the term. That disturbed me. Very much a word salad re branding of hysteria.
In this climate, we have a problem wherein women especially are dismissed and ignored. We have a problem with resources. We have various weird and wonderful physiological differences that so very many neurologists don't understand. I have encountered so many old, male neurologists. If it wasn't MS, MND or something well known as well I think I'd trust Google more than what I've experienced from neurologists.
I eventually did get answers. The real answers.
I have Ehlers Danlos Syndrome. I have associated problems with this which are systemic. It can impact joints, gastro motility problems can occur, it can cause all sorts of problems and co morbids that are terribly ignored and misunderstood. This condition is a genetic defect in collagen. Your collagen is everywhere. There is no reliable genetic test at this time but there's research. I'm diagnosed, not after being gaslit into oblivion first.
I have POTS - a co morbid. The Autonomic nervous system is messed up and doesn't function as well as someone without EDS. The symptoms can be horrific. I take lots of meds for this. Again - gaslit to high heaven. Until I found someone versed in it and had the testing. I also had skin biopsies explain why the full body screaming burning pain I experience was happening. Small nerve fibres actually being obliterated ( small fibre neuropathy). I have an autoimmune condition too which causes this. Gaslit again. Told by many I didn't have it before I was eventually diagnosed.
A biopsy of my lip gland showed immune cells had infiltrated and was destroying that. Lovely. This confirmed the autoimmune disease known to obliterate small fibre nerves. Not one neurologist I saw mentioned this before hand and suggested it was psychological. Again, I had to go private to access the lip biopsy and skin biopsy and the Autonomic testing showing y messed up autonomic nervous system and POTS symptoms.
Because I am very determined and my suffering was so severe, I could not walk away without learning everything myself and getting the answers.
Yes I'm still in a mess but by god i would be raging being told FND, knowing instinctively that's bullshit and there's a more defined explanation that is not word salad ' function, interpretation, enotion' rubbish.
I do understand that this term has been re branded somewhat and I absolutely believe people can have more sensitive systems than others that are triggered and they don't find a physiological cause.
The NHS found no physiological cause for all my complaints and I have a multitude of defined conditions now apparent. They simply didn't look there. Because it was out of the remit on their computer systems and computer said no whenever I asked them about any of this being a possibility.
My advice is to ask your friend if she's heard of EDS and POTS and go from there.
