My son is having involuntary leg spasms...I don't know if this is similar to yours at all but we haven't gotten a diagnoses yet....

He says that his legs doesn't hurt when it happens
but..

his legs go numb and then the spasm happens and it'd numb after
and it can go into the opposite leg...

He says it feels like twisting...

We have had two eeg's and a mri that came out normal

Now they want to do a EEG Video Monitoring

I'm just wondering are you having any of these symptoms that he has described..if so, what tests did you get to get a diagnoses?
