Honestly -- not really! Several people encouraged me to go to a specialist or PT but I was stubborn so I never got a diagnosis (my GP was clueless).
My self-diagnosis was some kind of muscle and/or tendon strain in my psoas / hip flexors. I squat very wide and deep so it wasn't a huge shock.
Net result was I couldn't squat properly for 4-6 weeks. I've added "prehab" stretches and it's mostly managed now, although if I go too crazy with volume I can feel it flare up.
