I am getting a really sore back. It's definitely my SIJs (sacroiliac joints)
From googling I think it's Posterior Pelvic Pain.
Has anyone else had SIJ back injections during pregnancy? I know they are usually done under x-ray guidance, and I obviously can't be exposed to x-rays during pregnancy. I wonder if/where they could do it under ultrasound.
Perhaps I would need to go privately? I don't know where to start, I don't have another midwife appointment for another 10 weeks 
Can I just phone my midwife's mobile number for advice?
