39 weeks, is this normal?

So today no matter what side i lay on or however i readjust myself while laying down, my arms from my elbows to my finger tips keep going numb. They go so numb that they’re physically painful even after i regain feeling, i can’t bend my right wrist, and when i touch my hands the white mark doesn’t go away for at least 45 seconds. Like my stomach has been numb, but now my arms? Is it worth a call to my obgyn?
