Persistent leg pain. Help!

Carolann
For the past two days I have a a pretty persistent pain in my lower leg it hurts pretty much all the time.
I don't know if it's soreness or what but because I'm on the Makena injection it makes me worry about blood clots.
I elevated my leg all night and it still hurts.
Should I call the hospital (my ob isn't open and the call well directly go to the hospital)
If so do I go to labor and delivery or the er?
Can I wait or should I go now?
Or should I not worry about it?
