I don’t know if I have covered this before, but those with neurological issues have a hypersensitivity to pain, especially touch.  When you barely touch them and they cringe in pain, it’s real.  Neurological issues irritate the nerve fibers.   So be gentle.  Of course check to make sure there isn’t something else going on, but know that if you move their leg or touch their arm and they say that hurts, it does.  Gentleness matters.
