my limbs are falling asleep

Megan
My doc said I have carpal tunnel so I am used to my hands falling asleep and hurting. I also have swelling in my hands and feet and a little in my face. I've had it since 15 weeks. I am now 29 weeks. 
But now, my limbs are falling asleep if I'm even sitting. My entire legs and arms. Is this normal? Should I be concerned?
