I do not accept authority's opinion, i.e. doctor diagnosis in this case... until or unless it makes sense, and then I hold off on procedures and the rest--if possible, go research, see what is the best course of action.
I did the research, hours of it, for the IT-band, piriformis, psoas, sciatica... and I have The Plan in the works.
What I do takes times; no quick "shot of cortisone" only to be repeated in weeks that tear down "more" connective tissue, but the work that I do -- when I do it -- pays off in increased strength: Mental, physical, other. (I don't know what "other" means here, but I'm leaving an open category to fill in later.)
