I have pelvic girdle pain for nearly 7 years now but it's almost impossible to get proper support for treatment
Oh god, yes - I hear you! I have suffered terribly with PGP starting when I was 19w pregnant with DS1. So just over 13 years ago. I am still suffering pain every single day and night of my life due to PGP. I must have had scores of GP appointments during that time. I have been told over and over again that "it usually resolves after birth". Indeed, but 'usually' inherently that means that sometimes it doesn't resolve! I just get surprised expressions, shrugs and as time progressed sceptical faces. Along with the either lightly hinted at or just outright blunt accusal of being a drug seeker. The entirely of my treatment has been a stretchy belt, referral to 2 courses of physio (that made it 100x worse) and mild painkillers (wouldn't want to actually treat my pain now, would we, steady on...)
My ex developed lower back pain during all of this - he was referred for a scan by his GP after the first apointment. Scanned within 2 weeks and surgery offered within 6 weeks. Fixed. And he got decent painkillers!
I was far more incapacitated and in more pain than he was at the time. I could barely walk and would wake every 30 mins all night long due to the pain. But a\ll I got was a sympathetic shrug and 'it's one of those things, it's very common in women...' Sadly, this also meant that my ex then decided that clearly I was massively exaggerating how bad my PGP really was. I was obviously a lazy cow who was pretending to be in pain for sympathy - if I actually had a problem I'd have been referred and operated on ASAP just as he was!
