May be a stupid question @Joel Watts, but did you guys rule out an avulsion fracture of the ischial tubercle? If it’s a high school athlete (or even collegiate really) it’s something you may want to highly consider if it hasn’t been done yet. It could be as simple as an apophysitis at the origin of the hammy that’s causing him the issue. I’m always of the mindset, especially with an adolescent joint, to rule out worst case (fractures, complete disruptions, etc) then that way I know what my next course of treatment will be. Also, unless it’s completely contraindicated for one reason or another, I use diagnostics sooner than later as a psychological “treatment.” Meaning, if you feel it’s mental with the athlete and can’t objectively explain away the pain/malingering component, get the picture of the athletes skeleton and show them there’s nothing structurally wrong. And, you can show the coach that nothing structurally is wrong. I’ve found there’s something magical that happens with an athletes complaint when you can prove to them objectively that “nothing is really wrong.” Then you can start throwing the kitchen sink at them as far as modalities, etc. Hope that makes sense.
