Hi joyfulpuddlejumper , isabelladeste and nikkilouise! Yes, please 'whinge' on here - no one else ever sees it that way as we're all on the same birthing ball...
joyful - I know what you mean, walked to post office a couple of weeks ago, normally 5 mins walk if that but it turned into an epic journey, like Frodo walking to fecking Mordor... Poor you having a pre-existing back condition on top!
isabelle -
at physio's exercises, I'm with iwill on this, he doesn't sound all that specialised in SPD/PGD... Don't worry about disregarding any exercises that hurt, all advice I've been given has been not to push on with such things! And opening your legs is usually on the banned list for SPD... Both you and miamama - sciatica can be difficult to distinguish from PGD, esp round the back. I could tell the difference cos i've had sciatica on and off for a while, so could tell how it was different but if I hadn't had it, I could have gone with that, as the pain was coming down from my lower back, thru buttock and down leg a bit predominantly on one side, so v like a description of sciatica. But they are treated differently!!! Hope your physio helps miamama!
*nikkilouise8 - ckeck out pelvic partnership.org for advice on all those bloody bothersome daily activities wot you used to take for granted, there are some good tips on there if you haven't already been.
mattsmama and iwill - my front bum bone also v sore recently, have been feeling under weather apart from that so haven't yet tried this but was thinkng that one of those ice packs you put in with chilled food might be superior to frozen food stuffs inc ice, as it won't melt and give the attractive just wet yourself look? I used one on face after a wisdom tooth removal, v soothing at time. Will let you know how it works once my get up and go returns... Hope you're feeling better soon, iwill, tis sucky to have UTI too 
alpinepony, glad to hear things are a bit better! I hate heaving to sit up straight too, but the pain that resulting from fidgeting about is a big encouragement to good posture! LOL at having to pull pants down for hunky GP, funny how used to this you get while pregnant (pulling pants down for random reasons, not hunky GPs...)
some day I will write a short post, I will honestly! Going to blame it on baby brain... and return to sitting on sofa in PJs staring blankly out window at rain.
