Is it normal to love to rub fabrics between my fingers?
As far back as I can remember, I loved to rub satin type fabrics together between my thumb and fingers. Such as the lining around the edges of blankets, shirts, labels, tags, etc.
At some point I went from that to rolling round things between my thumb and fingers.
Round things like pieces of dried spaghetti, pins, needles, pieces of plants, needle bearings, etc.
I'm wondering if this might be a sign of later disorders such as Parkinson's disease or Multiple Sclerosis. I have PD now. Has this happened to anyone else?
