Hi, @karencar. Our moderator, Nate, thought my experience with a mysterious lower back pain might suggest an option for your medical team to look into. In my case, my spinal surgeon and pain doctor recommended standard therapy for the pain -- PT for several weeks followed by an epidural of pain killer. Instead, my primary care physician suggested to first determine whether I had inflammation of my right sacroiliac joint -- a diagnosis that depended on ending the pain with injection of an anti-inflammation agent directly into the joint. That fixed the problem, and it has not recurred.

My case was different from yours in that no pain radiated down below my buttocks or down my leg. Though that might be possible from the inflammation I had, your doctors would have to tell you if my therapy might work for you. We'll be praying that you find relief soon and hope that you'll keep us posted on the treatment you received and whether it fixes your problem.
