hi i just wanted to post and let you know my experience, also an spd sufferer, for baby no1 i eneded up hospitalised as it got so bad, i was just in such pain i couldnt move. they tried to induce me at 38wks because of this it didnt work and i nearly ended up wtih Emergancy c section as baby got distressed, luckily they monitered me and he calmed down, they then offered me a c section or to go home and wait. i went back in once overdue and was induced but it took 3 days, had epidural, flat on back, legs in stirrups etc just maanged to avoid forceps and ventouse.
anyway i had months and monhts of pain after that.
it eventually settled, i had physio and i went swimming regularly and also focused on building up my core strength.
i had my pelvis x rayed when not preg and they did talk about pinning it! BUT i was lucky enough to see a specialist in spd! and he recomended taht if i had other children the BEST thing for spd was an upright normal delivery, hands and knees, kneeling etc and he said often a good delivery can help shift the pelvis back into the right position.
anyway i managed to do just that with ds2, kept mobile, used birth ball, laboured in the pool, lots of gas and air etc and i delivered him kneeling up leaning over the end of the bed (some people i know have done this with epidurals btw) and my pelvis was so much better afterwards!
went on to have ds3, same type of labour as with ds2.
then ds4 had in birthing pool, by far the best birth and he was 10lb 13oz!! my others were 9lb+
i think you need to do some research, speak to a midwife, i cant believe they havent referred you to physio!! INSIST and also have they given you a support belt? i have a narrow one specially designed for spd, what size are you? pm me and if i can find it you can have it :)
btw all of my other babies were 2+wks late!! each time i had had a favourable cervix for weeks, had sweeps etc but nothing had happened, in my case i wanted to avoid induction, despite the spd as i am allergic to the prostion gel they give you! i have to have my waters broken and of course this can lead to syntocin etc, i think by waiting my body was ready so after they broke my waters i then went into labour fine without syntocin.
i do really feel for you spd is awful :( but i have 5 now and thankfully most of the time my spd is fine, it seems to flare up when i get my period, i am assuming thats hormone related?
i do think having active births helped tho, so even if you go with the epidural try different postions, the midwives can help with this, also what about a mobile epidural, some hospitals do them?
