I had weird tingling in my fingers and toes once a few years ago. I am a complete hyperchondriac. I worried for a couple of weeks, worked myself up into a frenzy then went to see the doctor in tears thinking I'd got MS you name it. She said she thought there were many less serious things it could be, did basic bloods and my iron was chronically low. So maybe go & see the doc if not just to put your mind at rest. Most things tend to go away if you don't worry about them but it could also be something that is easy to fix (I had a weird finger cramp once and it was carpel tunnel symdrome or something which was made worse my too much time on the computer!
