@smn1 I understand your concern, but this question needs to be specifically answered for you by your physician. There may be many reasons something like this could happen and that may be a different reason for someone else depending on other health issues that may be involved with a diagnosis. If you have hardware screwed into your spine, it would be worth asking if that could be a cause, and how something like this may change over time. That's just a guess on my part. I did have ankle fracture hardware removed because my body seemed to be reacting to it.
