Original post by dipkaJust one phrase stands out in that to me. Where you say that it 'feels like electricity shooting around' I have something that feels exactly like that.
This is years ago, i got these pains like you described it ias like electricity shooting up my arm. It went from my fingers to elbow, sometimes to my sholder. I went to doctors and they said it's probably a trapped Nurve, and the 'cure' is to strap the 2 fingers together a bit like if youve broken a finger, then continue to do as much as things as you can normally, just with 2 fingers stuck together. Wait until you get none of the pain, then wait at least 24 hours with no pain before removing the tape. If it returns, simply repeat.
Basically doing that means I don't use the fingers, so it 'resets' the nurves, and they work again.
I have no idea how many times it's happend since but that's always what I do and it still works, if it dident id go back to the GP.
To anyswer your question I'd say it is likely that you have damaged a nurve yes as your symptoms are electricity are like mine. But maybe not injured, yes I do get times randomly when the pain comes back but it's fairly easy to treat as above-takes about a week of having it on, but is more affective the quicker I tape the fingers together from first feeling it.
I'm sorry I cant find any article online about traped nurves, but I suggest that you try taping your toes together, although I know you may struggle to walk as it's your big toe I don't know what elce to suggest. Other than go to your GP.
