This describes what I have exactly, and I've had it from being about 8 weeks pregnant. (Now 19 weeks!) It's just in one cheek, as it were and is sometimes so bad I stumble when walking, it's almost as though my pelvis gives way.
I went to the doctor and said I thought I might have PGP - she said no, probably sciatica and talk to the midwife. I spoke to the midwife, she ignored what I said about the PGP thing but referred me to the physio. Physio got back to me and said that I should go to a session for an hour with loads of other people where they would teach us exercises to help.
Now, is it just me or is that a crock? Everyone is assuming it's sciatica, which I don't think it is, the symptoms aren't the same. Now, am I being (pardon the pun) a PITA or does an hour lecture sound like a bit of a waste of time? Plus would be a nightmare as would have to take 19month DS who wouldn't really appreciate it.
Has anyone had PGP? Think this sounds like it? And what do I have to do to get someone to take it seriously?!
