Hi everyone! Thank you all for your kind responses and words of encouragement. I had my epidural into the sacroiliac joint on this last Wednesday. Since it's only been a few days, I don't want to jump the gun and say that it was a total success, but the pain in my lower back and front pelvic area is much less than it was before the injection. I have an appointment with the orthopedic doctor on Monday and we will know more after I visit with him. He is also doing a Dexa scan to check my bone density. I'll keep everyone updated. Here's hoping this helps someone else with similar symptoms!
