This is (I hope) no big deal but for the last three days I have a sensation that something is touching my left calf when nothing is touching it.
It's not painful or strong. It's just a sensation that something is on my leg. I keep bending down to check something isn't touching it, say a paper tissue has dropped down the inside of my trousers, or yesterday's sock or something, but nothing is there. It's intermittent and it feels like something the size of a finger tip is touching it very lightly.
Now I am lying in bed it feels more like a light involuntary muscle spasm though maybe but Imam not sure?
A bit wierd I know 
. Does anyone have any ideas please?
