Ohhhhh yes, lots and lots. As far as I'm concerned, ME is without doubt a neurological condition, at least on some level. Autonomic dysfunction clearly forms the basis of my condition, and it was explored by three different neurologists when I first got ill because it was so obviously central nervous system but with no obvious lesions on the brain.
Pressure in head, aching jaw, feeling like my right eye is numb and swollen. "water arm" - a cold wet watery sensation running down my right arm into my palm. Weird tiny vibrations in my muscles, tingling, itching (I get a sensation like there's a tiny spider on the end of my nose). My legs often have a pain in them, in the bone, that feels like they're cold to the bone but they're not cold, it's a dull nagging ache. I get a stabbing pain through my spine into my front when I've been upright too long, feels like I'm on a skewer.
I forget words, and my word association's all over the place - this morning I was trying to ask my husband why the ash tray was in the middle of the floor, and I kept saying "Why's the egg cup in the floor?"
My breathing patterns change, so sometimes my breaths are very far apart, and sometimes shallow and panting. I can't tell if my bath is hot or cold to the touch. I get twitches and ticks. I lose balance sometimes in the dark. I lose track of where my limbs are if I can't see them. I have problems with slow heart rate and low blood pressure, sleep patterns all over the place, sight issues depending on the day (fuzzy sight, or lazy eyes), temperature control problems (not being able to get warm, or feeling too hot even when it's cold), very dry nose, eyes and mouth or streaming eyes and excessive saliva. Palpatations, bowl and digestion trouble, loss of concentration, extreme muscle weakness, shaking, and post exertional malaise. Fight or flight response sometimes kicks in for hours, or days, meaning every time the phone rings I go into shock! V embarrassing!
It's so changeable, the neurological pathways must be constantly firing into the wrong places. For a month or more I could be housebound, and then one day, I'll just wake up and feel OK and go for a walk, and my muscles work! It's the weirdest thing, and it fascinates me. You can never fully appreciate what the nervous system does until it goes wrong, and then it just seems amazing that in most people it works without them even noticing it! Thankfully I very rarely get headaches, and I'm emotionally a pretty cheerful person, so you couldn't blame it on depression, it's just my wiring's wrong!
It appears that in the UK there seems to be a theory that ME has neurological symptoms, whereas other conditions that come under the CFS label may not display that way.
