I slid coming down the last two stairs a couple of weeks back and landed on my arse one of the stairs. Ok at the time, just a bit surprised and bruised-feeling, but since a few days later I've had lower back pain which has now 'moved' down into my buttocks and thighs - it hurts to stand up from sitting, getting in and out of car etc and I am waddling when I walk. Having googled it sounds like Pelvic Girdle Pain. Was dismayed to see it can go on for the rest of the pregnancy and even indefinitely. Has anyone found it goes away? I'm 25 weeks now and my midwife has said she can refer me to a physio if it doesn't improve - she didn't diagnose it as PGP specifically though.
