BTW, my right hip / ITB (/ SIJ?) are still popping all over the place, which is quite alarming. It means that I can either move the way healthy people move and cause a pop, or alter my bending movements and not pop. Two theories which I'm worried about:

(1) Once my lower back is fine - assuming that day comes - I'll be able to put more weight on it and take the load off my hip and get my hip joint stronger through correct movement and exercise.

(2) My hip is hopelessly buggered since my knees and lower back have not borne loads correctly for the last 2 years.

My knees are the weakest link right now, so I have ordered some knee braces from badbacks.com.au. I hope they arrive next week.
