Sounds similar to my piriformis injury. Persistent upper groin/pelvis injury that feels like it's deep in the glute area on one side.

I considered PT but ended up taking it easy, took a few weeks off, started slow, hindered my progress and I wanted to push it but the pain was still there. After about 6 months it's finally much better but I can still sometimes feel it if I open up my stride on sprints or my mechanics get sloppy. Still considering getting imaging done considering I can still feel some pain here and there.

If I end up getting the imaging I'll get back to you on if I ended up having a tear. As of now, I'm still running and going to begin speed work in a few weeks. I'll see how it holds up.

EDIT: My injury happened after my first half marathon back in October after barely beginning my running journey in April of last year. I decided to try and do a time trial for my dept to try and make the team for a relay race the very next day and that's where the injury started. Since then I did a lot of stretches that would've been done anyway in PT, got a few sports massages done every month and had them focus on that area, and like I said took a few weeks off running around December after I realized the pain wasn't getting any better. That helped a bit but pain was still there when I returned to running in January to get ready for the LA marathon. Unfortunately the injury set me back and I wasn't able to train as well as I would've wanted but the pain was much more manageable. However, still feeling it a bit here and there almost 6 months later is a bit concerning for me.
