hey, juliat,
i have symptoms such as yours, especially not being able to move well. it's like my brain is sending out the messages, but my muscles aren't receiving. i've experienced them anywhere from 3 days to 3 months.
they usually happen after an extremely stressful situation, or a culmination of same. the stress can be mental, emotional, or physical. onset is sudden - i'm ok going in, then my legs simply stop working. my best bet for recovery has also been rest and reduced stimulation.
lately, i've discovered that when some type of stress occurs that would normally cause my legs to become wonky, if i get angry about it, my body doesn't react with 'the slows', as i call them. it's led me to believe that it's an emotional repression that's causing such a reaction.
several times in the past few months (especially dealing with lots of docs and medical crap) i would just let my anger fly when hearing a diagnosis (i apologize afterwards, but it really feels good to just let it out), and i've been able to walk out of the office normally. before that, i'd walk out on wobbly legs, bent over like an old crone, moving very slowly. i've even been offered wheelchairs when personnel observed this.
now i'm thinking there is power in my anger, power that i haven't felt in my body for over 20 years - that's how long this has been going on for me. i got an mri after a doc noticed this, but was told everything is normal. they wouldn't schedule me for more than a routine mri, so i can only hold my own counsel on how 'normal' my brain/mind is.
just wanted you to know that you're not alone with this, and how i'm discovering there might be a connection between my emotions and my muscles. i think it is 'all in my head', but now i can see it as a more positive thing. this is something i have some control over, if i just allow myself to feel and express how i feel. it's been quite an eye-opener.
best to you with this, julia12. big hug.
