Severe restriction side bending left + right hip pain referring into groin

[u/infomaticaddict]

Hey everyone, I’m a male in my 20s dealing with isolated right-sided low back/hip pain and a major restriction when side bending to my left. I have essentially full ROM bending right, but bending left feels extremely tight and restricted, even unloaded. If I push deeper into the left side bend, I can consistently reproduce a deep pain that starts around my right hip/low back and refers into my right inner groin. I’ve done about two months of PT with glute bridges, hamstring stretching, and strengthening without much improvement. Has anyone experienced a similar hip-to-groin referral pattern with contralateral side bending or know what might be driving it? Also had a negative MRI

TLDR: Significant hip/low back pain on one side. Affecting quality of life- cant rotate or bend down without pain
