"Gluteal amnesia" sounds like when you forget about your butt!

I'm glad you are seeing a professional about this. I've been dealing with something similar, but it's gotten much better with regular Pilates and yoga. It's not something that I feel I need to see a medical professional about anymore. I used go to a PT (who is also a chiropractor) about it, and that helped.

Wishing you long-term (and quick) relief!
