More rarely but since before I was diagnosed, I get this in my legs/feet as well. I remember one instance in 1998 when my entire right leg went numb for a few hours and I could not walk on it. I have also had that happen again more recently but luckily for quite a short duration (minutes not days or even hours) and I was able to walk by locking my knee back (my knees hyper-extend after years of gymnastics/trampolining).
The subtitle above refers to the few examples of para(e)sthesia that I have seen in TV drama - all were surgeons that had to stop that work with at least one of them becoming a medical examiner (ME) instead. Luckily, all I need to do when it happens is work out how to get to a chair or my bed and/or power through it by continuing to knit whilst looking at my work rather than knitting by feel.
