I've had this with my last 4 pregnancies, including this one, and can be very painful.  My medical professionals (starting to wonder) refuse to diagnose spd or even refer me to a physio.

I have found that getting up and walking around for 5 mins helps, as does longer walks where you start out with pain, and just keep walking it out.  Laying on your left side in bed will help too, but even after a while of that, you will still need to get up and stretch out.

Gentle exercise and stretches will help, so will hydrotherapies, like walking in a swimming pool that is at least waist deep.  The extra gravity in the water means your muscles have to work harder, but the cushioning of the water means it hurts less. 

Heat packs in your pelvic region before a gentle work might also help.

hi, I've had SPD with my first pregnancy and now am 26weeks pregnant and experiencing it again(off and on at this stage).  All I got was physio support, belt and exercises etc but not really a help!  The best advice I can give you is to rest as much as you can (no walking,standing etc)!! It is the only thing that has helped my situation. Also no lifting, even shopping bags, washing baskets. I find this one difficult as I have a strapping 20 mth old!  I was also talking to my GP about it and he said in extreme cases, x-rays are taken to determine the 'gap' in the pelvis, and sometime a pin can be inserted to prevent the pelvis from becoming too unstable (which is what causes the pain) BUT this sounds horrible to me... I'd rather rest to lessen pain rather that go through that..sounds too risky for me!

Anyway hope that helps, My sympathies.. I know how painful it can be! By the way I was not at all mobile after the birth of my first child, but it was only for about 1week and then it improved quickly.  I was fine a month later! Nevertheless, everyone is different, and the range of pelvic pain is huge! Doctors say no two pregnancies are the same, let alone different people.

i too had this problem and found that going swimming or just standing in a pool helped soo much.. not just while in the pool but afterwards too. For me is disappeared after birth and gave me no problems during the birth.

Unfortunately there's not much that can be done about that condition so they won't be able to help you anyway. It's not that no one knows about it, it's that it's one in the too hard basket. The good news is it doesn't give you problems during the birth.

And I like your description of how if feels. You're right, I always described it as feeling like the bone is fracturing or dislocating (have had fractures and dislocations before, feels very similar actually, when it gets bad enough)

I'm linking the advice on minti about it here as well as the advice link to the question. Hope it helps.

While it is normal to have aches and pains, by all means if you feel like no one is listening, speak up! Keep in regular touch with your physio and possibly seek a second opinion. Rest as much as you can.
