Restless leg? Sciatica? What is this??!

I am plagued by numbing, jumpy, tingling feet/calves/butt/lower back. These symptoms seem to be a mix of RLS and Sciatica. It’s not painful or Id say textbook Sciatica. But it not quite RLS either because it goes all the way down past my calves. God help me, could it be both?!

I am currently sleeping on an ice pack for my lower back/butt, icy socks for my feet, and massaging my calves throughout the night. Unable to sleep on my back, only on my side -but leaning severely forward. (Once my belly gets bigger this position won’t fly.)

I’m 13w4d along, earlier than these symptoms are typical. Sleeping is really difficult. Even a 1/2 hr facial (lying on my back) is near impossible. HELP!!
