Sacroillitis?

I was wondering how a patient gets diagnosed with Sacroillitis?

Sherrine, I believe you mentioned you have this condition. What kind of doctor diagnosed you with this and how?

I occasionally have buttock pain, tailbone pain, and lower back pain. But I did fall on the ice many times while living up north.

My GP ordered an xray and I was told my tailbone area is fine. I'll be asking her at my next appoinment if the xray might have missed the possibility of my having tarlov cysts. I'll ask her at my next appt about having an MRI to look for this.

Thanks!
