PP leg pain

So I am having pretty bad leg pain. It goes from my hips all the way down into my ankles and feet. It's like a really bad radiating ache. It started almost a week ago and seems to just be getting worse. It's especially bad at the end of the day and makes it hard to get comfortable sleeping. I thought it was from carrying around (and bouncing and rocking and swaying with) my 11 lb baby but it hurts so bad and now I am not sure. I am 1 month PP. Has anybody else experienced this??
