vibrations on body

Just a little note on my stimming. I'm constantly rubbing and massaging my skin, or scratching with whatever I can find. I've got backscratchers and head scratchers, but while they are good at scratching, there is very little pressure. So, I've ordered a handheld massager. I'll use it as a massager for my calves, which get really sore because I walk like on my toes a lot. But a friend who has an autistic son said it really helped him because the vibrations on his body help him to relax.
