tingling feeling in legs, what to do

Hey ladies, so I'm 35 weeks tomorrow and today I've been feeling like a tingling feeling in my legs feels like they will go numb, they haven't it just hurts. The best way I could describe is like trying to spit gum through a straw... also I've been having a cramp in my right but cheek, I'm scared because my legs hurt lol is this normal or should I go to the hospital???
