Thank you all so so much for getting in touch with all this advice. Honestly I'm willing to try absolutely anything just for a bit of restbite!
Elmtreemama - I'm so so sorry to hear you're struggling and really hope that they get some relief for you too! It is absolutely awful and definitely not the glowing pregnancy I expected...!
Emmaluggs - That has crossed my mind once or twice along with 'how on earth do I manage this for the next 12 weeks?!' I am going to look for a private chrio/osteo this evening. I called my local chiro the other day as thought they could help but they said they weren't comfortable working in pregnancy so stupidly assumed this would apply to them all which apparently is absolutely not the case (huzzah!)
Adviceneeded - Thank you, I really appreciate it! Will look into private treatment. Any relief would be worth every penny!
DeathMetalMum - Oh I am so sorry to hear yours flared up again, you poor thing! Baths have definitely been a huge help - though getting out of them is definitely getting harder and harder!
Cookiesandcream - So sorry to hear you've suffered so much too, that sounds awful. Your advice was hugely helpful! I'd already called my local chiro on the off chance they could help and he said he wasn't comfortable working in pregnancy so wouldn't go ahead (fair enough!) but I never considered that others might be. Let alone that there is a website with approved people listed!! This is so so helpful and I'll be making an appointment asap so thank you so much!!
Nightmanagerfan - Thank you! I had a look and have now ordered something similar. Turning over in bed requires a 24 step process, some expletives and a few tears so this looks like it'll help tons!
Garman - I've sent a few emails today to try and book some in! I'll start calling first thing tomorrow!
HotPenguin - I'm definitely going to do that first thing tomorrow. The physio I spoke to was based at my local hospital and is a Womans health physio and discussed manipulating my pelvis back into place and then binding it so hopefully they'll be good but will be nice to have something in the meantime!
Sadly there is no space for a desk job at work. I inquired about it a couple of weeks back but my job is clinical and I can't do any aspect of it unless I'm up and about with patients. (They're also not being the most helpful bunch at the moment which is a touch infuriating!)
BastardMonkfish - Sadly I think this may be the case. My GP saw me shuffle into her office and sad straight away that she thought the best course was to sign me off until my maternity leave started. I'm a bit desperate to get back in any capacity because I hate being off sick. Equally I know that I'm not the safest practitioner when I'm unable to mobilise. She has, however, agreed to placate me and sign me off week by week so that if I wake up cured, I can return. That could totally happen... right!? 
MonkeyPuddle - That's the one I'm waiting to hear back from. It is SO good to hear that it helped so much!! Gives me a bit of hope that this might ease a bit!!
delilahbucket - Oh you poor thing. I am so sorry to hear you're still suffering. I will absolutely be doing this!!
Daffodil21 - Thank you!!
Soubriquet - Oh you poor thing, that sounds awful! I must admit the bath is the only place I get some mild relief. (Definitely nearly got stuck in there the other day though...!) I will make sure I do those things! Thank you.
ListenToChickens - Thank you so so much for coming on to reply to my post! I'm so sorry you are still suffering too!
Oh my goodness yes, turning over in bed is a bloody military operation with ever increasing pain. Then by the time I've made it to the other side normally I need a wee...!
I've got a plastic bag on my car seat which definitely helped. I find getting out easier than in. Although sadly my mangers have been totally useless thus far, I am NHS and I have 11 years service so I do get full sick pay. So although I absolutely HATE using it, I'm lucky enough that I don't have to worry about that side of things and can focus on just trying to survive the next 12ish weeks without going totally insane...! Thank you again for your post!
TheFairyCaravan - I am so so sorry to hear how much of a struggle you have had with this. I feel like I'm falling apart and mine has been a matter of weeks!
I fear you may be right on the work front. Their view was that unless I can go back full steam (which includes running to emergencies etc) then I'm not fit to be there. Today I took a trip to tesco because I ran out of cat food. I parked right outside the store and only got the cat food - nothing else. By the time I got home I was in so much pain I honestly had no idea what to do with myself. I'm a solo mother by choice following an IVF pregnancy so finding it a touch tricky around the house on my own but thankful that my family are close by and popping in intermittently to help with housework etc. Thank god for online shops too eh! (When I actually remember everything!)
Strangely I didn't consider ice - I will try that now!
Thank you so much for your message and tips. Wishing you all the very best and I hope you get some relief.
baggies - So sorry to hear your daughter had this, especially with so little help available! Glad she is doing so much better now. Thank you for your reply and the tips!
bsquared - Thank you for those ideas! I'm going to order the ball and the roller now and give them a go! I've also got a pregnancy massage booked for later on and hadn't thought to bring that forward!
I'll also look up some pilates and send some emails out this evening about it all!
So glad to hear it is easier to manage in your current pregnancy! Hope all goes well with little one!
blitzen - It is definitely very cruel that moving around in bed and getting up are so painful and yet we have to wee so often! (And it hardly seems worth the effort half the time!)
Oh that is interesting. I shattered my coccyx a few years ago and it never properly healed which was picked up on a CT scan last year. Then at 12 weeks pregnancy I slipped down the stairs and went from top to bottom. My one injury was that my coccyx suffered some further damage and it was already pretty bad in there so I wonder if that could have something to do with it!
Thank you so much for the reassurance that it went away too!
Honestly thank you all so much for your replies. I felt totally and completely overwhelmed the last couple of days. I think the trouble sleeping isn't helping me handle the fact it is so painful and I felt a bit daunted by the fact this is likely here to stay to a degree for a while yet. Having read all your posts I don't feel so alone and have lots of things to try and feel much more in control!
Thank you all so much.
For those still suffering I really hope you get some relief soon. x
