First and foremost Functional Neurological Disorder causes a lot of pain, personally heat really helps me, if I get cold, I can be bed ridden. but I know of people who are polar opposite. It’s a very weird condition, it makes your body do things you did not realise were possible. I have video I might post of my toes going round in circles.

Brain fog… this is so annoying you know what you have to do or what the answer is, but you can not retrieve the answer.

Convulsions, this are painful and not much fun, personally I have three levels of them

Just my fingers are twitching, neck, toes and legs.I find it hard to walk
Im shaking all over it moves through my body the whole time, I have no control of it at all, it can also go into my face as well making it very hard to talk.
My body goes into semi paralysis in that I can not more my arms or hands voluntary it can also go into my lungs paralysing them making it very hard to breath, I can also be in severe convulsions where my body will be banging against the floor. It
