Yes, there is a good point in what @MonkeyOwl mentioned.
Considered mentioning this in your other thread as it’s a common confusion or misconception.
The nervous system is an intricate network which runs throughout the body, and both regulates and receives constant feedback from the many physical and energetic systems.
It’s not a separate thing from the energy system or the rest of your body, in the same way that the energy system is not separate from the physical body.
Everything is intertwined, so if your system is overloaded or overwhelmed in other ways, that always has the potential to affect the nervous system (or other systems in your body) and vice versa.
That is one reason any sort of unskilful or overwhelming energy work can be harmful to the body’s systems, including the highly intricate and interwoven network we call the ‘nervous system’.
From another discussion:
Also, it’s very understandable and common to feel a stronger than usual aversion to things which one experiences whilst feeling overwhelmed and associates with it.
It is actually one sign of particular types of central nervous system activity being involved, though again, that is always intertwined with the many other physical and energetic systems.
(for example after some types of damage from viral infections as you’d mentioned those in the other thread, or after overwhelming your system energetically in particular ways)
It can be a natural instinctive response whether or not the associated things are actually causing the issue.
Perhaps some form of trauma release or healing might help with any healing your system needs, in addition to allowing adequate rest and and anything else you find of help of course.
Wishing you all the best and maybe we can help more.
