Yes, that’s the pain described exactly!! There is a minimally invasive SI joint fusion surgery involving titanium implants that I am considering. I am 73 and have had back issues since 1975 when my spondylolithsesis was discovered after something “gave way” slipped while pulling my son out of a high chair table. I have a very high tolerance for pain which isn’t necessarily a good thing. My back doctor commented he was surprised I was still walking when he saw my recent x-ray. I’m having lumbar injections on Monday, but I feel I need SI joint ones instead. This growing up thing is highly overrated! ( Irene5)
