I quizzed my midwife about some odd groin pain that kinda ran from my groin down into my upper thighs, she told me that there are two large nerves that run down both legs from the groin to the thigh, and as the muscles loosen up due to the increase in hormones and the body's preparation of carrying a baby, I could look forward to more 'shooting' type pains occurring in this area. She added that it is completely normal, and very common during pregnancy.
