It's MS. I get them too - in my legs.

quite often finger tips between fingers and toes and on knuckle joints. Don't know if this is also a symptom but when I am experiencing pins and needles and numbness I find it hard to work touch screen technology. its like im running my finger over the screen and the machine cant register it

I get this when I bend my neck and look at my toes as well, was told by my neurologist that it is a side affect of MS. It doesn't hurt fells like pulling and a shock going down my spine.

My lesion is on spinal column in neck told to not flex neck when I can avoid it

Yes I use to get that in my throat.
