I had an MRI this past May by my former OS. The results ended in an EVIL Euflexxa series. Since, I have hired a new OS who wants to do another MRI before my TTT. The Euflexxa didn't change the anatomical structure of my knee, nor did it do any good anyway leaving me worse than I was pre-injection. Why would he want a repeat MRI done? Also, what difference could there possibly be between the side-by-side comparison of my 'old' and new MRI's in just a matter of 3+ months? Tyia
