Ok, call me stupid but before xmas and trying to fix back problem i've had for yrs, i came across SI joint dysfunction while searching the web. A lot of my symptoms fit the bill and so i started on exercises to correct my SI joint. Guess what, i now have SI joint dysfunction on top of the original problem. My consultant wants to perform l5-S1 fusion and after steroid injections into SI joint that lasted only 2 wks claims that if I had S I joint dysfunction then the steroids would have fixed it. From what I've read this doesnt always seem the case. What are your thoughts re: fusion of L5-S1 when already have SIJD? What can/should i do to fix SIJD and should i do it before or after fusion? Fusion is an option. I have others (i hope) but that is different story.
