Understood. Thank you for your response. So although the adductor is the point of failure, it is unlikely to be the cause?
In general my flexibility is very good. The only exception is the abduction movement on the side in question (which is approx. half of what it was formerly). The same tightness-to-the-point-of-failure can be experienced in the adductor/hamstring in straight leg hip flexion and opposite hip internal rotation.
The following have been observed: anterior pelvic tilt, weak gluteals & adductors, tight hamstrings & iliopsoas, SI joint pain and now oedemas in both greater trochanters.


I have been working on my glute and adductor strength through bridges, squeezes, clams, static holds etc. But I do not understand what is likely to be the primary cause in all of this. I don't seem to be getting anywhere at all with the adductor...
