After I had my S.I. joint fused to my pelvic bone 2 1/2 years ago, I tried to tell my neurosurgeon about the severe pain I had over the S.I. area especially when any pressure was put on it such as laying down on it. The P.A. I had to speak to made a rude remark about it and probably didn't even mention it to the surgeon. I mentioned it to the surgeon at a 6 month check up and it was ignored completely. finally now after 2 1/2 years my dear rheumatologist ordered steroid injections in bilateral hips and bilateral S.I. joints and I'm finally getting some relief from the pain. The take away from this is that if your surgeon doesn't do his job then seek out another doctor who will before you have to endure years of pain.
