S-I pain vs hip replacement

For Matt: I truly had 2 problems at once: hip arthritis & S-I dysfunction. I
had the S-I dysfunction in the past treated with prolotherapy so was familiar.
Unfortunately, I delayed THR a bit for personal reasons, that flared the S-I.
I recently completed a round of prolotherapy---seems to be resolving---takes
a bit. THR in Sept. --- I live in Western NY state, so this harsh Winter has been tough,
but am slowly getting better. I feel the S-I dysfunction is difficult to diagnose and
I wasted a yr. of other treatments before doing prolo 17 yrs. ago after the birth of my
daughter---one fairly typical mechanism of injury. Sometimes it is difficult to ascertain specifically
where pain is coming from.
Good luck
