I have 2 suggestions. 1-ask your dr. for Pramipexole. I take (2) .25mg at dinner and by bed they've calmed down. 2-I use Gold Bond Maximum Strength Pain and Itch Relief Cream with 4% Lidocaine during the day. If I catch it at the start I can stop it.

Ifs so rough! Try magnesium and potassium

I do, most of the time just in my right leg I have a constant urge to stretch.
