old and ignorant, and creaky too

I've been having some issues with my right hip during yoga. It doesn't hurt when I'm just walking around, or even during basketball, but whenever I do a hard stretch like a right side split I'll notice. I was afraid I had a stress fracture or something, because the last time I had persistent pain it turned out I had a stress fracture in my left foot (although that healed by itself). Anyway, my doctor thinks I have early arthritis in my hip. Ugh. She thinks all that gymnastics as a kid might have contributed, because gym inflicts a lot of trauma on your joints (well duh). Now they tell me. I guess the 4-year-old me wouldn't have known what arthritis was anyway.
