I had it now and again with number DS1. I rember the first time I got it, and thinking 'oh my god, how will i cope with labour'. With DD1, I got it a little more, when sneezing, coughing etc. Im 37 with number 3, and get it every bloody day!! Mainly when I turn over in bed. It takes me a few minutes sometimes, just to turn over. Also if i've been sat at my desk in work for too long, its uncomfortable standing up. I found gently rubbing the area eased it a bit quicker.
Yes, it's a sharp, twangy feeling and I suffer from hay fever so it's all day long at the moment. I have learnt to kind of curl up and brace myself when I sneeze. Poor little thing must think there's an earthquake! However, it hurts less as the weeks pass
