I can't recall. I will find out though. Indeed the MYRSA was in close proximity on my back to the bad disc but I have had a problem with my back since High School. I need to get my MRI to the Doc as he claimed he has not seen it. I have a call in for Monday for the Neurologist regarding the testing as it strikes me that he should not of ordered these test until he ruled out the issue with my back diagnosed after CT scan as Degenerated Disc L5-S1. Am I wrong?
