Is this a shallow hip socket and if so could it be causing my hip pain?

Hello all! I am 26F height: 5'2" weight: 100lbs medications: Buspar Adderall Trazodone Clonazepam Diagnosis: ADHD Panic disorder General anxiety disorder Difficulty falling asleep I have been having ongoing left hip popping and hip pain. This has become an issue for about the past year and a half and has gotten worse as time goes on. I have been through physical therapy once and now going to physical therapy again. I am very physically active both at work and at home. I walk on average 5 miles a day, do leg and hip strengthening exercises I have gotten from physical therapy previously at home at least 4x a week but these seem to not be helping. I get a significant pop in which I feel a 2 series clunks more than pop. The first pop is a very big clunk in which it definitely feels like my leg gets shortened and the second does feel like it could be muscle moving over bone. It happens so often that I now only get mild pain at that moment and then fades into moderate pain and soreness in my deep buttocks and higher up at my SI joint. Initially it was significant pain and it would cause me to limp for a day and then moderate pain for a week. After the popping, I immediately feel 2 other pops that feel like it's resetting my joint and muscles back in place. My left hip randomly pops while walking, every time I climb up stairs or walk downstairs as well as when I rotate my leg inward. I have a hard time walking on uneven ground because it causes pain. I do have mild hyper mobility. I had x-rays taken and the radiologist report stated there are no abnormalities and everything looks fine so I was referred to physical therapy for snapping hip syndrome by my PCP. The instant I showed the popping to the physical therapist he had a very shocked horrified look on his face. He said it is not snapping hip syndrome at all and that he can feel my joint separate and come back into place, a subluxation is what he called it. I'm no radiologist but just from glancing at my x-rays it seems pretty clear to me that my left femur only sits halfway into the socket. Could a shallow hip socket be causing this? Is this a subluxation? Or is it really just snapping hip syndrome? if it is a subluxation that's constantly occurring will physical therapy help stop it? Or what are the long term complications from this continuing to happen. tl;dr: continuous clunking/snapping/ popping left hip causig pain, radiologist says normal hip anatomy but looks like a shallow socket to me. is it subluxation or snapping hip syndrome? TIA!! ETA: I do get mild swelling around my hip every time this happens.
