Possible physical/neurological issues associated with autism

Just a curious question really to try gauge how strong physical/neurological issues can be linked to autism. For example I am red/green colour blind and have slightly webbed toes and fingers. I know hyper mobility is another indicator but does anyone have either or both of what I’ve described about myself? (This may seem like an odd question I know)

  • There is often synaesthesia linked to autism. In my case it was stronger in my childhood but I still experience it. Words and numbers have tastes. For this reason it was very hard for me to concentrate on math. Numbers taste like fruits and berries so I had a fruit salad in my mouth during algebra. And I was compared to my colleagues and told: "you see how good she is doing? You can do it too! Just put more effort, don't be so lazy." And I had no idea how other kids so easily ignored tge fact that 7 tastes like a green apple and 8 like a plum.
