Hi someone has kindly pointed in your direction after a post on another forum
I am the exact same. My feet and toes also sit exactly like yours - turned in.
I think that it's something worth looking into to see if anything makes sense of your symptoms; I know that I didn't think I had EDS or think I was hypermobile, either...
I have several friends with EDS and knew a enough about it to think that there was no way that I had it, but after Courtney proved me wrong I found out that not only am I hypermobile, EDS fits my medical history and current symptoms extremely well.
I hope you'll be able to find some answers!
