I have always had a weird thing and now I'm wondering if it is common in EDS patients.... When I put weight on my foot or bend my hand back, these strange white bumps emerge under the skin on my heel or the heel of my hand. They are not hard and my guess would be that they are some kind of fat deposits.
As a child, I told my doctor that the bumps appeared when I bent my hand back and he said, "Then don't do that." (The first in a long line of soooooo helpful doctors!) When I tore my calf muscle more recently, the physical therapist freaked OUT at the sight of the bumps and said she had never seen anything like them.
