@bigmuscle72 Welcome to Connect. I follow a physical therapist from Europe on facebook, and he talks of conditions where there seems to be a disconnect of symptoms and trying to define if something is a spine issue or a muscular issue causing a compression. I agree, that before you do surgery, you need to be reasonably sure that it will address the cause of the problem. Here is an article on his website that may shed some light on what is called Lumbar plexus compression syndrome. Of course there could be spine issues, but there can also be other muscular issues and since you have had surgeries and not bearing weight equally on both your legs, that certainly could favor muscle spasms causing problems and differences in strength across both sides of the body. You can connect with the author on facebook and comment on one of his posts. He has responded to my comments before.
