Definitely go to a rheumatologist. My regular practitioner never pointed me in their direction, I was actually pushed to see a rheumatologist when I ended up in urgent care in extremely bad pain with nothing to explain it in X-rays. The rheumatologist got to know me, and ran extensive blood tests, and diagnosed me with undifferentiated connective tissue disease. I hope this helps!

A rheumatologist or a physical therapist could probably help. I had super bad joint pain in my ankles, knees, and hips for years and ot turned out that some of the joints weren't in sync with how far they extended so I went to a PT for a few months and they gave me some exercises that did wonders.
