Hiya, I'm 25 weeks pregnant. I have a four and a half year old daughter who was born naturally but the wrong way up - the pain in my back was excuciating as I was in back labour for 37 hours. My back has been hurting on and off with this pregnancy as I expected it might, my coccyx has been painful and have been feeling like my back would give way. Now my coccyx still hurts, but I have shooting pains through the front left-hand side of my pelvis and down the front of my leg and also in my buttock. Anyone have any ideas what it could be?
