Dew,
So sorry this has happened.
Could you have been dozing off when this happened?
I think that would make it a myoclonic jerk.
I'm not a doc, as you know.

But, I think I'd say you should call yours!
Report this oddity, before it fades from memory!

I hate to feel as if I'm trying to goad you into action when you're not feeling well.
With all that you're going through, Your Doc needs to know what's going on with you!
If you can't, have Hubby call for you.
(we can have so many little oddities, ticks, jerks, swelling, pain that's like a ghost moving through you) that it's difficult to get this across to your doctor.
Especially if he's not an RSD specialist.

I'm lucky enough to have one, every time I think I'm telling him something new, he says,"He knows I've got that". Just by looking at me and talking to me.

I wish everyone had a doc like him.

Be well,

pete
