Possible physical/neurological issues associated with autism

I had goosebumps and feeling close to vomit when touching velvet, when I was a kid. There were velvet seats in cars, I had sickness as soon as I entered the car, sat there and the overwhelming mix of smells- petrol and some "air fresher" made me truly sick it was a torture for me. Now it's not that bad. 

That’s really interesting, when I think about biting knifes and forks or someone else doing it I can force myself to have goosebumps, useless party trick really 

I have better than average colour vision, I used to have better than average hearing too, now it's normal for my age. I do have slight hypermobility, mostly in my fingers.

I have heard that high numbers of allergies is associated with autism in women, if that the case it would explain why I'm known at the doctors as 'the woman who's allergic to everything'.

I don't have webbed toes or fingers, but my feet are flipper shaped, although I swim like a brick.

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. 

Yeah I can do that too, it’s quite comfortable to squat with your knees resting against your chest, is this a form of hyper mobility? It might seem a bit of an odd way to relax but when you need to be lower to the ground and stable it’s the best way of doing things 

Suspect it is primarily due to stress, plus not drinking enough water or drinking regularly enough.

May also be affected by restricted diet in some people.

Thanks for that, I know digestive issues are common such as constipation, not sure if this is due to a difference in wiring or it’s due to increased anxiety among autistic people. 

I’m 57 and can still climb easily, my big toes are shorter than my second ones, it seems upset my balance. I can still squat for long periods with my knees up to my chest, I often do this when working on vehicles, we we’re always told that sitting on concrete would give us piles, don’t know how true that is, but no plies!

My coordination is not good, never could understand why others were able to catch, throw or kick a ball. If I’m sitting I often sit with my legs curled up under me. Other people just don’t seem so flexible.

I don't have the same issues as you describe but did a bit of research as these were not traits I had prevously seen attributed to autism.

There are quite a lot of research articles about the colour blindness link to autism but all the ones I saw had a sample size of 20-30 people which I consider low for meaningful results.

There does seem a corrolation however:

https://pmc.ncbi.nlm.nih.gov/articles/PMC5492848/

The present findings showed that both the autistic and AS groups display a high proportion of color vision defects—about 30% of the sample studied.

I note that they differentiate on autism and AS (Aspegers Syndrome) based on higher IQ & speech skills = AS, lower = autism. They acknowledge it is controversial but wanted a clearer way to see if there is any corrolation.

As for the webbed digits, there also seems to be a link to autism:

Genetic factors may play a role in influencing both webbed toes and autism risk. Some genetic syndromes associated with syndactyly, such as Smith-Lemli-Opitz syndrome, have also been linked to an increased likelihood of autism. This overlap suggests that there may be shared genetic pathways or developmental processes that contribute to both conditions. 

I note this is still an area of active research so the results are far from set in stone as of yet.

What you describe just sounds like (uncommon) autistic traits after reading this - all related to the wiring of your brain and the effects on your bodies development.

Thanks for raising these subjects - I really had not seen them linked with autism before.
