Fellow preggies! I've had a really bad pain in my left calf all day long and I've been stretching it out and massaging it and nothing seems to work. The pain is only when I walk, which makes my waddle a lot worse! Any else experience this? It's not sciatic pain cause I've had that, and it's not a Charlie horse because I've had those too and the pain just doesn't go away.
