Hi lonely autistic,
The best thing I can think of right now is stress relief. No, it may not be an actual cure for physical symptoms of hypersensitivity, but it can help you feel better overall in general.
One idea that doesn't cost a lot of money is an Epsom salt bath. If you only have a shower, there's another way I discovered by accident ... you can at least give yourself a facial by using a mixture of Epsom salt and water. Make sure not to get any into your eyes ... that really hurts. What I mean is using a cotton ball to apply a combination of Epsom salts and water onto your face and not rinsing it off right away.
Try to have the Epsom salts soak into your skin ... the salts consist of magnesium sulfate ... both minerals are very good for your health, especially for autistics from what I read. I need to do this tonight, because I've had a headache today, and Epsom salts can help with that, too.
If you have more money to spend, you might consider going to a massage therapist at your local salon or spa. Yes, it sounds weird, especially if you don't like being touched. But I tried it, and find it very relaxing.
I look forward to seeing other people's ideas as well.
Hope you will feel better soon.
