help...!

Morgan
I am having a hard time walking & I have 5 weeks left. 
I have sciatica down the back of both my legs, I have just now started getting Charlie Horses in my calves & then since about 24 weeks(or so) I have been having these weird leg things where my legs just fall asleep and hen HURT. 
Any tips to help me out? I'm going to doc tomorrow. But I can't walk.
