That’s not all it can lead to. 😦
This is the story of my life, partially. Despite being crazy flexible, I live with excruciating pain in both hip flexors. When it flares up, it’s awful. When it’s fine, I’m okay, but it’s the kind of pain you NEVER forget. I’ve lived with it since I was a gymnast and I still have it. 😦 C’est la vie.
