I am so sorry for how you have suffered. I just found this site & am planning on adding my story. Long story short, I was dx'd with osteo in 2014, following a routine back surgery (osteo was in L5, S1 & discitis in associated vertebral discs) The first time, I was on pic line antibiotics for 7 mo. A year or two later, I was on pic antibiotics for a couple months. I fear it has returned. You are 100% correct - there are no words to describe the pain. I am very precise when I am asked to scale my pain because that acute level is one you NEVER forget. Best wishes to you & your lovely family.
